Adipose-derived mesenchymal stem cells (gAD-MSCs) are promising candidates for veterinary regenerative medicine, yet the characterization of gAD-MSCs from locally adapted Indonesian goat breeds remains limited. This study aimed to isolate and characterize gAD-MSCs from Peranakan Ettawa (PE) goats using tissue explant culture. Subcutaneous adipose tissue was collected from the base of the tail of healthy PE goats (n=3). Primary cell outgrowth from explants was observed by Day 5, displaying characteristic fibroblast-like, spindle-shaped morphology and strong plastic adherence. Serial passaging to Passage 3 (P3) yielded a morphologically stable, homogeneous cell population. Assessment of cellular metabolic activity via the resazurin assay demonstrated sustained cell viability and a statistically significant increase in metabolic activity between Day 3 and Day 5 (p < 0.05). Furthermore, functional clonogenic capacity, evaluated using the colony-forming unit (CFU) assay, showed continuous temporal expansion of colonies over 14 days, yielding an average of 52.0 + - 4.1 colonies per dish. These findings confirm that expanded gAD-MSCs P3from PE goats maintain characteristic mesenchymal morphology, sustained metabolic activity, and clonogenic capacity. This work provides a baseline cellular profile of PE goat gAD-MSCs, supporting their potential use in veterinary regenerative medicine and tissue engineering.
