Human embryonic stem cells (hESCs) are pluripotent cells capable of differentiation to representatives of all three germ layers. Includes: Isolation of Primary Mouse Embryo Fibroblasts; Thawing and preparing p1 MEF feeder plates; Preparation of MEF- Conditioned Medium (MEF-CM; Microdissection Passaging of hESCs; Bulk passaging of hESC; Cryopreservation of hESCs; Thawing of hESCs; Karyotyping. - [Read Human Embryonic Stem Cell Protocols]
Mononuclear phagocyte progenitor cells derived from femoral and tibial bone marrow are propagated in the presence of M-CSF. This macrophage growth factor is secreted by L929 cells and is used in the form of L929 cell conditioned medium. The progenitor cells proliferate and differentiate through monoblast, promonocyte and monocyte stages before maturing to macrophages. At this time the cells become firmly adherent to the culture vessel. - [Read Isolation and Culture of Mouse Bone Marrow-Derived Macrophages Protocol]
