This protocol describes the isolation of fibroblasts from mouse embryos. Mouse embryonic fibroblast (MEF) cells are used as a feeder layer for the culture of mouse embryonic stem (ES) cells to help maintain them as pluripotent stem cells. The inhibition of ES-cell differentiation provided by the MEF feeders appears to be due to their production of leukemia inhibitory factor (LIF). - [Read Isolation and Freezing of Primary Mouse Embryonic Fibroblasts (MEF) For Feeder Plates]

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]
This protocol describes the preparation of mouse embryo fibroblasts (MEFs), which can then be used as feeder cells to maintain embryonic stem (ES) cells in the undifferentiated state. - [Read Preparing Mouse Embryo Fibroblasts Protocol]
Skin fibroblasts are incorporated into 3-D collagen lattices containing the test compounds. An inhibition of lattice contraction indicates a possible toxic effect which is verified by trypan blue exclusion for cell viability. - [Read Human Skin Fibroblast/Collagen Lattice Cytotoxicity Test]

Potential embryotoxicity is assessed by monitoring the effect of the test compound on total protein synthesis, and DNA synthesis in cultured human foetal lung fibroblasts. Rat lung epithelial cells can be used to determine cytotoxicity of select compounds because of their ability to metabolise xenobiotics. - [Read Lung Cell Assay Protocol]
