Discovery of a periosteal stem cell mediating intramembranous bone formation and fracture healing (single cell RNA-Seq)

CTSK-mGFP positive cells from Day 6 old mouse femurs were sorted as single cells into 384 well plates pre-loaded with unique barcoded RT-primers. After sorting, cells were snap frozen on dry ice before being submitted to the New York Genome Center (NYGC) for cDNA synthesis and library preparation. The FACS profile for all the sored cells were collected to co-relate with gene expression. Overall design: Mouse femur was obtained from mice within the same litter. Femur samples was subjected to collagenase digestion, and single cell suspension was obtained. The samples were stained for FACS antibodies and single cell sorting was performed into two individual 384 well plates. The experiment has two replicates from two independant animals. The samples were always kept discrete.
