简介：
Overview
This protocol outlines the isolation of pig adipose-derived stem cells (pADSC) from subcutaneous adipose tissues, focusing on their multipotency and differentiation capabilities. The pADSC are utilized to explore adipocyte differentiation and transdifferentiation into various mesodermal, ectodermal, and endodermal lineages for regenerative applications.
