Hello! I am having problem in sorting BMDCs from a heterogenous population of murine hematopoietic stem cell which have been cultured in RPMI+10% FBS+ 1% PenStrep with FLT3/L (for differentiation) for 9 days. Every time I have sorted the BMDCs, either the cell morphology completely changes or the cells die after a day. Any help regarding this will be appreciated. Thank you.
