Scientists introduced a customizable collagen I-hyaluronic acid (COL-HA)-based hydrogel platform for the encapsulation of MSCs. Cells encapsulated within COL-HA showed a significant expansion of their secretory profile compared to MSCs cultured in standard (2D) cell culture dishes or encapsulated in other hydrogels.

Scientists focused on the communication from MSCs towards osteoclasts-like cells in vitro. MSCs seeded on a calcium-phosphate biomaterial or undergoing induced apoptosis produced a conditioned media favoring the development of osteoclasts from human CD14+ monocytes.

Scientists demonstrated that hPDLSCs, hBMSCs and hDPSCs could directly differentiate into neuron-like cells without passing through a mitotic stage and that they shrunk dramatically and changed their morphology to that of neuron-like cells through active neurite extension.
