Development of Human Mast Cells from Hematopoietic Stem Cells within a 3D Collagen Matrix: Effect of Stem Cell Media on Mast Cell Generation

Mast cells (MCs) arise from hematopoietic stem cells (HSCs) that mature within vascularized tissues.Fibroblasts and endothelial cells (ECs) play a role in the maturation of HSCs in the tissues.Due to difficulties in isolating MCs from tissues, large numbers of committed MC precursors can be generated in 2D culture systems with the use of differenti
