Abstract

Background: Umbilical cord-derived stem cells (UC-MSCs) are essential cell sources for cell-based therapies in regenerative medicine. Hypoxia is a key element of the stem cell niche and crucial for the preservation of UC-MSCs properties. The normal growth conditions for UC-MSCs are under atmospheric oxygen concentrations of 20–21%. However, the administration of UC-MSCs in inflammatory conditions provides oxygen-deficient environments. Thus, treating UC-MSCs with low oxygen exposure provides them with more survival and recovery potential. Objective: In this study, we assessed the impact of hypoxia incubation for 12 h on the UC-MSCs proteome. Methods: UC-MSCs were isolated from UC patients regarding informed consent. At passage 5, in 80% confluent, UC-MSCs were incubated in 5% O2 for 12 h. The morphology of UC-MSCs was assessed using a microscope. The level of FGF-2, FGF-8, TNF-α, and HSP-70 were analyzed using ELISA. Results: Hypoxic condition could change their morphology and enhance the cellular density compared to normoxic conditions in vitro. The level of FGF-2, FGF-8, TNF-α, and HSP-70 were significantly increased after the hypoxic condition of UC-MSCs compared to normoxia. Conclusion: Our findings suggest that the hypoxic condition was able to induce survival capacity and soluble molecules secreted by UC-MSCs.

Abstract

Background: Chronic inflammation is central to the pathophysiology of Type 2 Diabetes Mellitus (T2DM), contributing to the progression of metabolic dysfunction characterized by hyperglycaemia and insulin resistance. This study aims to investigate the therapeutic potential of the hypoxic MSCs secretome (SH-MSCs) in reducing inflammation of a T2DM rat model. Methods: T2DM was induced in Wistar rats through a high-fat diet (HFD) followed by streptozotocin (STZ) administration. A total of 24 healthy male Wistar rats were randomly assigned to five groups: healthy control, T2DM, T2DM + metformin, T2DM + SH-MSCs. Results: SH-MSCs significantly reduced IL-18 mRNA expression, a key indicator of proinflammation, and suppressed the expression of AP-1 mRNA, a crucial proinflammatory transcription factor. Conclusion: These findings highlight the therapeutic potential of SH-MSCs as an alternative approach to alleviate inflammation in T2DM.

Abstract

Background: Mesenchymal Stem Cells (MSCs) are cells that have the multipotent ability to undergo self-renewal, differentiate and secrete various bioactive substances, such as chemokines, proteins, microRNAs (miRNAs), growth factors, and cytokines. Conditioned medium of MSC is a medium resulting from cell culture enriched with the secretome of the cultured cells. MSC-CM treated with certain factors can increase the production of growth factors such as VEGF and PDGF, which play a role in angiogenesis and tissue repair. Modification of MSC-CM with bioactive compounds can be a promising strategy to increase the effectiveness of MSCs in medical therapy. Therefore, this study aims to examine whether these herbal extracts can modulate the production of pro-inflammatory cytokines (TNF-α, IFN-γ, IL-1β, IL-6) and growth factors (SDF-1, PDGF, VEGF) in MSC conditioned medium. Methods: This study used a pre-post research design with four treatment groups. Medium culture of MSCs treated with Nigella sativa (doses of 10 µg/mL) and Phyllanthus urinaria L (doses of 25 µg/mL), which were cultured for 24 and 48 hours. Measurement of cytokine and growth factor levels was carried out using the Enzyme-Linked Immunosorbent Assay (ELISA) method for quantitative analysis. Results: The data reveal distinct patterns in the modulation of protein levels, particularly for SDF-1, IL-1β, IL-6, TNF-α, and IFN-γ, which are critical players in inflammation and tissue regeneration. Conclusion: This study showed that the Nigella sativa and Phyllanthus urinaria L extracts in modifying conditioned medium of Mesenchymal Stem Cells is significant release of pro-inflammatory cytokines and growth factors.
