Abstract

Introduction: Umbilical cord-derived mesenchymal stem cells (UC-MSCs) accelerating wound closure by increasing VEGF and PDGF level leading to re-epithelialization, cell infiltration, and angiogenesis. It has been found that MSC-conditioned medium (MSC-CM) can enhance migration of fibroblasts in scratch assays. However, the effect of MSC-CM-induced serum injury (MSC-CM-S) formulated in gel to accelerate wound healing remains unclear. This study aims to evaluate the effect of several doses of topical gel of MSC-CM-S in accelerating wound healing. Methods: The MSCs were cultured medium-supplemented serum injury of wounded rat (8:1) to get MSC-CM-S. The topical gel of MSC-CM-S was made by base gel supplemented with MSC-CM-S. Eighteen Wistar rats were randomly assigned into control (C) and treatment groups (T1, T2). Groups were received serum-free medium gel (C), 25 µl MSC-CM-S in topical gel (T1), 50 µl MSC-CM-S in topical gel (T2), twice daily for 9 days. PDGF and VEGF level and fibroblast density were measured by ELISA and HE staining at day 3 and 6, respectively. Results: This study showed that there was significant increase of VEGF and PDGF level along with a significant increase of fibroblast density at day 3 and 6. The T2 showed optimum enhancement level of VEGF, PDGF and fibroblast density. Conclusion: Topical gel of MSC-CM-S was effective to accelerate wound closure by enhancing PDGF and VEGF level in full-thickness skin defect rats.

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: Extracellular vesicles, particularly CD63+/CD9+ Mesenchymal Stem Cell Exosome (MSC-Exo), have emerged as crucial mediators of intercellular communication and potential therapeutic agents, including regenerative medicine and immunomodulation. However, the precise isolation and purification of MSC exosomes pose critical challenges. Tangential Flow Filtration (TFF) has gained recognition as an efficient exosome isolation method, offering scalability and versatility. In this study, we address the pressing need for standardized exosome isolation methods by comparing two distinct TFF-based protocols for isolating CD63+/CD9+ MSC exosomes based on filter size pore order. Methods: MSC-Exo were conducted from the Stem Cell and Cancer Research Laboratory (SCCR Indonesia), which were then processed through TFF using different filter sizes and orders. There are two filtration methods compared, first, MSC-Exo was filtered with 1000-5-500-300-100-50-10-5 filter order. Second procedure, MSC-Exo was filtered using 1000-500-300-100-50-10-5 filter order. Result: Flow cytometry analysis revealed variations in the percentage of CD63+/CD9+ in the MSC-Exo based on filter order. The results indicate that the choice of filter order significantly influences the size range with the highest concentration of CD63+/CD9+ MSC-Exo. Conclusion: This research underscores the importance of optimizing TFF-based isolation methods for CD63+/CD9+ MSC exosomes, especially in the order of filter pore size.
