Abstract

Human Wharton’s jelly‐mesenchymal stem cells (hWJ‐MSC) are an emerging potential source of stem cells derived from the umbilical cord. Previous studies have shown their potential as treatment for traumatic brain injury and Parkinson’s disease. However, no study has yet investigated the effect of hWJ‐MSC injections in countering spatial learning and memory impairment in aging rats. The effect of hWJ‐MSC injection on young rats is also unknown. The objective of this research was to analyze the effect of an hWJ‐MSC injection on spatial learning, memory, density of putative neural progenitor cells (pNPC), and neuronal apoptosis in the dentate gyrus (DG) of young and aging rats. Injection of hWJ‐MSC did not change spatial learning and memory in young rats until two months post‐injection. This might be due to retained pNPC density and neuronal apoptosis in the DG of young rats after injection of hWJ‐MSC. In contrast, injection of hWJ‐MSC promoted both spatial learning and memory in aging rats, a finding that might be attributable to the increased pNPC density and attenuated neuronal apoptosis in DG of aging rats during the two months post‐injection. Our study suggests that a single injection of hWJ‐MSC might be sufficient to promote improvement in long‐term learning and memory in aging rats.

Abstract

Female reproductive system showing the fastest signs of aging. The ovarian aging characterized by a decrease in follicular development. Stem cells are undifferentiated cells and can form a variety of different cells as the foundation of tissues and organs. Previous studies reported that Bone Marrow Mesenchymal Stem Cells (BM-MSCs) transplantation can restore follicular development in damaged ovarian rats. This study aimed to analyze the number of follicular development in aged rats and to analyze the capability of human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) to improving follicular development in aged rats. This study used 3 mature rats (4 months old), and 9 nine aged rats (22-24 months old), Spraque Dawley (SD) strain. They were divided into four groups. The first and the second group was mature rats and aged rats without injection. The third and the fourth group was aged rats injected hUC-MSCs dose 106 cells/kgBW and hUC-MSCs dose 107 cells/kgBW. The injection carried out 4 times at 3-month intervals. The parameters observed were follicular development and homing image of hUC-MSCs in ovarian tissue. The results showed that the number of follicular developments in aged rats 22-24 months decreased significantly compared to mature rats 4 months old. Injection of hUC-MSCs at dose 106 cells/kgBW and 107 cells/kgBW did not increase follicular development in aged rats. hUC-MSCs did not found in ovarian tissue. It could be concluded that aged rats 22-24 months old no longer productive indicated from the number of follicular developments and corpus luteum decreased. The injection of hUC-MSCs intravenously did not indicate an improvement of follicular development in aged rats 22-24 months old.

Abstract

Osteoarthritis (OA) is a chronic disease of the joints and bones due to trauma or other joint-related diseases (secondary). Synovial inflammation commonly causes disturbance in joint homeostasis, which is associated with OA. Enzymes such as aggrecanase and metalloproteinase generate cartilage damage, mediated by tumor necrosis factor (TNF-α) and interleukin (IL)-1. Pro-inflammatory cytokines, including TNF-α, IL-1β, and IL-6, are responsible for regulation of the extracellular matrix, cartilage degradation, and apoptosis of chondrocytes. This study aimed to observe the cell viability and expression level of matrix metalloproteinases (MMP-1 and MMP-3) and tissue inhibitor metalloproteinases (TIMP-1 and TIMP-2) in human chondrocyte cells (CHON-002) induced by IL-1β. CHON-002 was induced with IL-1β (0.1, 1 and 10 ng/mL) as an OA model. The viability of the cells was measured with a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxyme-thoxyphenyl)-2-(4-sulfophenyl)-2H-tetra zolium (MTS) assay, while expression of MMP-1, MMP-3, TIMP-1, and TIMP-2, was evaluated by RT-PCR. The viability of IL-1β-induced CHON-002 (CHON-002- IL-1β) cells at day 1 and 5 showed that treatment with up to 10 ng/mL of IL-1β was not toxic. Expression of TIMP-1 and TIMP-2 in CHON-002-IL-1β was lower compared to control, while that of MMP-1 and MMP-3 was higher compared to control. These results indicate that CHON-002 treated with 10 ng/mL IL-1β has expression patterns consistent with chondrocyte damage, so the CHON-002-IL-1β system may serve as a model for MMP induction in OA.

Abstract

Breast cancer (BC) is the most prevalent type of cancer among women and one of the major causes of cancer mortality in women. Metastasis in breast cancer (BC) occurs due to immunosurveillance deficiency, including impairment of natural killer (NK) cell maturation. Conditioned medium (CM) from human Wharton's jelly mesenchymal stem cells (hWJMSC-CM) is known to possess anticancer activity. The CM of co-culture of human recombinant IL-2 treated NK cells and hWJMSCs is expected to boost anticancer activity toward BC cells which can be analyzed from the effect of CM towards secretion of effector molecules and expression of BC cell apoptosis-related genes, and cytotoxic granules in human recombinant IL-2 treated NK (IL-2 NK) and hWJMSCs (IL-2 hWJMSCs). TNF-α, IFN-γ, perforin, granzyme were measured by ELISA, while the inhibition of cell proliferation was measured by MTS assay and BC cell apoptosis by flow cytometry and apoptotic gene expression by RTPCR. CM from co-cultured hWJMSCs and IL-2 NK cells inhibited NK and BC cell proliferation, increased expression of Bax and p53 and decreased the number of Bcl-2 in BC cells. In conclusion, CM of co-culture IL-2 treated NK cells and hWJMSCs induce apoptosis in BC cells as indicated by increased Bax and p53 expression and decreased Bcl-2 expression.

Abstract

Edible bird’s nest (EBN) is often consumed as a health food due to its suggested health benefits, including anti-aging effects, however the mechanism is still unknown. This study investigated the effect of EBN extract using long term expansion bone marrow-derived mesenchymal stem cells (BMMSCs) as an aging model. Passage 5 (P5) and passage 8 (P8) BMMSCs were treated with EBN extract, and their proliferation, senescence-associated β-galactosidase (SA-β-Gal) activity, and expression of p16INK4a were analyzed. Treatment of BMMSCs with EBN extract decreased population doubling time (PDT) in P5 but not in P8 BMMSCs. In P5 BMMSCs, 200 ppm EBN extract increased BMMSCs proliferation, with PDT reduced by 27.6%. However, 200 ppm EBN extracts did not affect P8 BMMSCs proliferation, although it increased BMMSCs viability. Treatment of P5 and P8 BMMSCs with 200 ppm EBN extract decreased SA-β-Gal activity by 54.8% and 47.1% of the control, respectively (P<0.05). Levels of p16INK4a expression were 5.4-fold lower in P5 BMMSCs treated with 200 ppm EBN extract compared to control (P<0.05). Similarly, treatment of P8 BMMSCs with 200 ppm EBN extract reduced p16INK4a mRNA level by 7.9-fold compared to the control (P<0.05). In order to investigate the pathway of EBN extract inhibition, we further analyzed IL-6 and NF-κB1 expression. Treatment of P5 and P8 BMMSCs with 200 ppm EBN extract reduced IL-6 mRNA levels by 7.9-fold and 2.1-fold of control, respectively (P<0.05). We found that 200 ppm EBN extract reduced NF-κB1 mRNA level approximately 2.4-fold both in P5 and P8 BMMSCs (P<0.05). Thus, EBN extract reduces markers of senescence, indicated by decreased SA-β-Gal activity and p16INK4a mRNA level, and this correlated with reduced messenger RNA levels of the pro-inflammatory factor IL-6 and the transcription factor NF-κB1.
