Abstract

Heart disease is the leading cause of death worldwide. Within decades a limited process of cardiac cell regeneration was under observation. Embryonic stem cell (ESC) shows great potential for cell and tissue regeneration. Studies indicate that ESC has the potential to enhance myocardial perfusion and/or contractile performance in ischemic myocardium. However there is still challenge to evaluate the issues of teratoma. Then induced pluripotent stem cell was invented by introducing four transcriptional factors (Oct4, Sox2, Klf4, c-Myc). iPSC was created from murine fibroblast and then differentiated into cardiomyocyte. Reprogramming the adult cell could be performed in full, partial or direct reprogramming. Several studies add the significance by reprogramming the cells through more efficient techniques. However several limitations are still remained.Keywords: cardiomyocyte, reprogramming, iPSC, fibroblast

Abstract

BACKGROUND: A population of circulating Endothelial Progenitor Cells (EPCs) has been reported to play important role in maintaining endothelial function and integrity. Since EPCs culture is crucial and an optimized medium is currently available. Therefore we conducted a study to investigate whether stable angina subjects peripheral blood-derived EPCs could be cultured in this medium. Here, we performed study to detect EPCs characteristics and extracellular signalregulated kinase (Erk)1/2 Mitogen-Activated Protein Kinase (MAPK) pathway as possible underlying pathway for EPCs proliferation.METHODS: Peripheral blood EPCs from 8 stable angina subjects were cultured in an optimized medium with/without addition of supplement for 1 or 3 days. Then, the membrane of cultured EPCs were detected with immunofluorescence method for CD34, Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2) and CD133. Colony forming unit (CFU) enumeration was performed. XTT Cell proliferation assay was performed to assess EPCs growth after 1 and 3-days culture. The western blot analysis was performed to detect possible activation of Erk1/2 MAPK.RESULTS: Number of EPCs and CFU cultured for 3 days were significantly higher than the ones cultured for 1 day (p=0.012). EPCs membrane markers from stable angina subjects were detected as well as CFUs were formed. There were significant increase of EPCs number, CFUs number and phosphorylated-Erk2 amount when the groups with and without supplement were compared (p<0.05). Meanwhile U0126, a MAPK Erk1/2 (MEK1/2) inhibitor, significantly inhibited the supplement-induced EPCs number, CFUs number and phosphorylated-Erk2 amount (p<0.05).CONCLUSION: Our results showed that ERK2 MAPK signaling pathway might play an important role in supplement-induced peripheral blood EPCs proliferation in subjects with stable angina.KEYWORDS: endothelial progenitor cell, EPC, p42, Erk2, proliferation

Abstract

BACKGROUND: Coronary artery disease (CAD) remains as the world number one cause of morbidity and mortality. Endothelial progenitor cells (EPCs) are known to be involved in vascular biology. Current review briefly summarizes the basics of EPCs and its clinical use in CAD.CONTENT: EPCs were firstly isolated in 1997 and involved in neovascularization. Further evidence defined EPCs into two distinguishable groups, namely: myeloid angiogenic cells (MACs) and endothelial colony forming cells (ECFCs). Common cardiovascular drugs, statin, angiotensin-converting enzyme (ACE) inhibitor, and their combinations, showed beneficial effects on EPCs. Likewise, the incorporation of EPCs upon CAD intervention management had been recently studied. Intramyocardial EPCs implementation and anti-CD34 antibody-coated stents could provide a promising option for refractory symptoms in CAD.SUMMARY: Association between EPCs and CAD is very dynamic and complex. EPCs could serve as both therapeutic target and agent in CAD patients. Subsequently, a universal definition of EPCs is needed for greater research in the future.KEYWORDS: atherosclerosis, coronary artery disease, endothelial progenitor cells, neovascularization

Abstract

Rheumatic heart disease (RHD) occurs due to sequelae in the form of damage to the heart valves from the failure of acute rheumatic fever (ARF) therapy. Heart valve damage can cause various complications such as congestive heart failure, arrhythmias, pulmonary hypertension, atrial fibrillation, endocarditis, which can cause death. The study aimed to assess the association between clinical characteristics and valve lesion and rheumatic heart disease severity. The study was an analytic observational with a cross-sectional design of 73 patients with definite RHD from September 2019 to March 2020 in Dr. Soetomo Regional General Hospital. The majority of patients were female (80%, p=0.235) 30–39 years old (34%, p=0.157). The mean age was 42.08±12.16 years. The majority of patients have low socioeconomic status (78%, p=0.025) and rural dwelling location (70%, p=0.138) over three-quarters of patients living with more than four people in the same house (75%). Multivalvular lesions (90%, p=0.003) and severe RHD (77%) were present predominantly. In conclusion, low socioeconomic status and multivalvular lesions are associated with rheumatic heart disease severity. KARAKTERISTIK KLINIS DAN JUMLAH LESI KATUP PADA DERAJAT KEPARAHAN PENYAKIT JANTUNG REUMATIKPenyakit jantung reumatik (PJR) adalah penyakit yang terjadi akibat gejala sisa berupa kerusakan katup jantung dari kegagalan terapi demam reumatik akut (DRA).

Abstract

Background: Atherosclerotic lesions develop as the result of an inflammatory process initiated by endothelial damage. Endothelial progrenitor cells (EPCs), which is derived from bone marrow, participate in endothelial repair and new vessel growth. Cardiovascular pharmacotherapies have been shown to improve overall numbers and function of EPCs in patients with cardiovascular risk and cardiovascular disease. Studies have reported that statins exert beneficial effects on EPCs by enhancing EPC proliferation and differentiation. Thus, we require a research to analyze the effects of three different statins on EPC proliferation. The objective of this study is to analyze the effect of statins on EPC proliferation from peripheral blood of stable coronary artery disease patient.Methods: This is an in vitro true experimental post-test only control group design. The mononuclear cells (MNCs) were isolated from peripheral blood of stable coronary artery disease patient and were cultured in CFU-Hill medium for three days. Then samples were put into four groups, simvastatin experiment group, atorvastatin experiment group, rosuvastatin experiment group and control group. Each experiment group was divided into three subgroups with different doses, 0.1 ?mol/L, 0.5 ?mol/L, and 2.5 ?mol/L then incubated for 48 hours. EPC proliferation was evaluated afterwards with MTT cell proliferation assay. Immunocytochemistry method was performed for EPC identification to evaluate expression of CD34+. CFU-Hills were observed to confirm functional characteristics of EPC. Data were analyzed by independent T-test and ANOVA.Results: MTT cell proliferation assay showed a significant increase of EPC proliferation in simvastatin, atorvastatin, and rosuvastatin groups compared with control group (0.237±0.007, 0.248±0.01, 0.231±0.008 vs 0.17±0.008, p<0.05). It also revealed significant difference in EPC proliferation between each experiment groups, which atorvastatin showed the highest effect. EPC proliferation in atorvastatin is higher than simvastatin group (0.248±0.01 vs. 0.237±0.007, p<0.05), and simvastatin is also higher than rosuvastatin group (0.237±0.007 vs. 0.231±0.008, p<0.05). CFU-Hill counts demonstrated highest number in rosuvastatin group, followed by atorvastatin, and simvastatin. Immunocytochemistry showed positive expression of CD34.Conclusion: Statins increase EPC proliferation from peripheral blood of stable coronary artery disease patient. Atorvastatin showed the highest EPC proliferation, followed by simvastatin, and rosuvastatin. Each statins increased EPC proliferation dose-dependently.

Cardiovascular pharmacotherapy has been shown to improve the amount and function of EPC in patients with cardiovascular risk. Many studies report that statins have a beneficial effect on EPC by increasing the number and function of EPC, including the migration function. Therefore, we conducted a study to analyze the effects of three different statins on EPC migration. Objective: To analyze the effect of statins on EPC migration from peripheral blood of stable coronary artery disease (SCAD) patient. Methods: This was an in vitro true experimental post-test only control group design. The MNCs were isolated from peripheral blood of SCAD patient and were cultured in Stemline II Hematopoietic Stemcell Expansion Medium in 3 days. Then samples were put into four groups, simvastatin 0.5 µmol/L, atorvastatin 0.5 µmol/L, rosuvastatin 0.5 µmol/L and control, then incubated for 48 hours. Immunocytochemical examination was performed to evaluate expression of CD34+. On the 5th day of culture, 5x105 cells per group were transferred to the upper chamber of the transwell system, then incubated for 1 day. Cells that migrated to the lower chamber of transwell system were calculated by automatic cell counter with typhan blue coloring. Data were analyzed by independent T-test and ANOVA. Results: The results of independent T-tests showed a significant increase in EPC migration in the simvastatin, atorvastatin, and rosuvastatin groups compared with the control group (234000 ± 1290.994, 265000 ± 1290.994, 203000 ± 1290. 994 vs 174071.43 ± 1426 785, p <0.05). EPC migration also differed between statin groups, where the highest effect was found in the atorvastatin group. EPC migration in the atorvastatin group was higher than the simvastatin group (265,000 ± 1290,994 vs 234,000 ± 1290,994, p <0.05), and simvastatin was higher than the rosuvastatin (234,000 ± 1290,994 vs 203000 ± 1290. 994, p < 0.05). Immunocytochemical examination showed a positive expression on CD34+. Conclusion: Statins increase EPC migration from peripheral blood of SCAD patient. Atorvastatin showed the highest EPC migration, followed by simvastatin, and rosuvastatin. Keywords: EPC migration, simvastatin, atorvastatin, rosuvastatin

Abstract

Background: Number and function of Endothelial Progenitor Cells (EPC) are reduced incoronary artery disease (CAD) patient. EPC as progenitor of mature endothelial cell has important role for angiogenesis and neovasculogenesis. Dysfunctional EPC partly because of oxidative stress. Decreasing oxidative stress with antioxidant especially with sweet purple potato extract and vitamin as easily found in Indonesia, may improve EPC migration to ischemic organ in stable CAD patient. Purpose : To analyze effect of sweet purple potato (Ipomoea batatas L.) extract and vitamin C on Endhotelial Progenitor Cell in Stable Coronary Disease patient. Method: This is experimental post-test control group study. Mononuclear cells (MNC) are isolated from peripheral blood of sample, and cultivated in medium for 3 days, immunofluorescence assay with CD34 as a marker for EPC. EPCs divided into sweet purple potato extract group (1 and 25 mcg/mL), vitamin C group (10 and 250 mcg/mL) and control, incubated for 2 days. 5x105 cell taken from each group and place in upper chamber of Transwell system. EPC migration was assessed in lower chamber of Transwell system after 24 hours using automated cell counters. Statistic testing using ANOVA. Results: EPC migration was increased significantly in sweet purple potato extract and vitamin C compared with control (3.03 ± 0.01, 2.15 ± 0.03 vs control 1.21 ± 0.04, p<0.01). Increased dose of sweet purple potato extract and vitamin C shows significantly increased of EPC migration (1.81 ± 0.02 vs1.47 ± 0.04 and 3.03 ± 0.01 vs 2.15 ± 0.03, p<0.01). There is significantly diferentiation between sweet potato purple extract and vitamin C (3.03 ± 0.01 vs 2.15 ± 0.03, p<0.01). Conclusion: Sweet purple potato extract and vitamin C increased EPC migration dose-dependently. Sweet purple potatao extract induces EPC migration better than vitamin C.

Abstract

Sel Progenitor Endotel (EPC) merupakan kelompok sel yang memiliki kekuatan angiogenik yang kemudian dikenal sebagai pilihanpengobatan seluler untuk mengimbas perbaikan lapisan intima pembuluh darah. Berdasarkan beberapa kajian sebelumnya, jumlahEPC di pasien angina pektoris stabil lebih rendah dibandingkan dengan individu yang sehat. Di samping itu, EPC juga dikenal sebagaiperamal independen terhadap perjalanan penyakit jantung koroner. Tujuan penelitian ini adalah untuk mengetahui peran transduksiisyarat ERK1/2 terhadap proliferasi EPC yang diambil dari darah tepi pasien angina pektoris stabil dengan imbasan pemberian faktorpertumbuhan. Penelitian ini merupakan kajian percobaan melalui uji laboratoris dengan pendekatan atau rancangan control grouptime series design. Penelitian dilakukan di Laboratorium Prodia Stem Cell Indonesia di Jakarta pada bulan Januari 2014. Sampeldarah tepi diambil dari delapan (8) subjek relawan pasien angina pektoris stabil yang memenuhi patokan kesertaan dan sebagaipembanding digunakan delapan (8) unit darah tepi yang diambil dari orang yang bukan pasien angina pektoris. Metode sel mononuklear(MNC) dari delapan (8) pasien angina pektoris stabil diisolasi selama satu (1) atau tiga (3) hari di medium tertentu dengan atautanpa penambahan suplemen. EPC yang dihasilkan dan dicat dengan metode pengecatan imunofluoresens untuk mendeteksi CD34,Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2) dan CD133. Pemeriksaan proliferasi sel XTT digunakan untuk menilaipertumbuhan EPC setelah kultur antara 1−3 hari, sedangkan perhitungan Colony Forming Unit (CFU) digunakan untuk menilai fungsiEPC kelompok yang terbentuk setelah dikultur antara 1−3 hari. Analisis western blot dilakukan untuk mendeteksi aktifasi ERK1/2.Hasil mengecat imunofluoresens mengukuhkan seluruh petanda membran EPC termasuk CD34, VEGR2 dan CD133. Jumlah rerata EPCyang berdaya hidup di pasien angina pektoris stabil lebih rendah dibandingkan dengan pembandingnya, yaitu masing-masing 5,77×103dan 23,40×103. Jumlah EPC baik kelompok pasien angina pektoris stabil dan yang pembanding meningkat secara bermakna denganperangsangan faktor pertumbuhan. Hasil western blot menunjukkan bahwa ERK1 diekspresikan lebih tinggi pasien angina pektoris stabildibandingkan pembanding. Fosforilasi ERK2 terdeteksi di kelompok pembanding dan menguat secara bermakna seiring waktu denganperangsangan faktor pertumbuhan. Fosforilasi ini dihambat oleh U0126. Di pasien angina pektoris stabil, fosforilasi ERK2 terdeteksipada perangsangan faktor pertumbuhan setelah kultur selama tiga (3) hari.
