Stem cell education for medical students at Tongji University: Primary cell culture and directional differentiation of rat bone marrow mesenchymal stem cells.

Stem cells are cells that can self-renew and differentiate into a variety of cell types under certain conditions. Stem cells have great potential in regenerative medicine and cell therapy for the treatment of certain diseases. To deliver knowledge about this frontier in science and technology to medical undergraduate students, we designed an innovative practical experiment for freshmen in their second semester. The lab exercise focused on rat bone marrow mesenchymal stem cell (BMSC) isolation, cell culture and differentiation, and it aimed to help students master the aseptic techniques for cell culture, the basic methods and procedures for the primary culture and passage of BMSCs, the basic procedure for the directional differentiation of BMSCs into adipocytes and their subsequent identification by oil-red-O staining. This lab exercise is a very meaningful and useful introduction to stem cell collection and manipulation and inspires medical students to deepen their understanding of translational medicine and regenerative medicine. © 2017 by The International Union of Biochemistry and Molecular Biology, 46(2):151-154, 2018.
