The BMP virtual forum is an online series of webinars meant to allow BMP-researchers to communicate about their work, as the biannual BMP conference has been postponed due to COVID19 restrictions. Last week, Tim was invited to talk as a junior scientist working on BMPs and stem cells. In his talk, Tim unveiled the skeletal cell atlas he developed, a single-cell genomic reference of the developing and adult skeleton, and demonstrated its use by performing an in silico case study of BMP signaling between skeletal cells.
