research [Influence of the stiffness of three-dimensionally bioprinted extracellular matrix analogue on the differentiation of bone mesenchymal stem cells into skin appendage cells].
This study observed that bone marrow mesenchymal stem cells cultured in three-dimensionally bioprinted hydrogels with higher stiffness, like 3A8G, tend to differentiate more into hair follicle cells compared to those in less stiff hydrogels, like 1A4G.
