简介：
Overview
This article discusses the generation and administration of therapeutic spherical aggregates, or spheroids, of mesenchymal stem/stromal cells (MSCs) primed under xeno-free conditions. These methods aim to enhance the efficacy of MSC therapeutics by addressing challenges related to cell retention and functionality post-transplantation.
Key Study Components
