Enhancement of Chondrogenic Differentiation in Bone Marrow-Derived Stem Cell Spheroids by Cuminum cyminum Methanolic Extract: Insights into Concentration-Dependent mRNA Expression and Gene Clustering Analysis

Abstract

Background/Objectives: Cuminum cyminum L. has been utilized as a medicinal plant for centuries. This research sought to examine the effects of cumin methanolic extract (CMT) on the chondrogenic differentiation of human bone marrow-derived mesenchymal stem cells. Methods: Spheroids were generated using human stem cells and cultured with CMT at concentrations between 0 and 1 µg/mL. Morphological assessments and cell viability tests were conducted on days 1 and 3. Chondrogenic differentiation expression was evaluated through quantitative polymerase chain reaction, Western blot, and RNA sequencing. SOX9, FAM20B, COL2A1, and COL1A1 mRNA expression levels were determined using real-time polymerase chain reaction. Protein expression was analyzed via Western blot. Results: Throughout this study, the spheroids maintained their integrity and shape. No significant variations in spheroid diameter were observed among the groups. CMT treatment enhanced the expression of SOX9 and FAM20B. Conclusions: The methanolic extract of Cuminum cyminum facilitated chondrogenic differentiation in human bone marrow-derived mesenchymal stem cells by modulating SOX9 and FAM20B expression. This indicates its potential application in cartilage tissue engineering.
