Mouse cardiac fibroblasts have been widely used as an in vitro model for studying fundamental biological processes and mechanisms underlying cardiac pathologies, as well as identifying potential therapeutic targets. Cardiac FBs are relatively easy to culture in a dish and can be manipulated using molecular and pharmacological tools. Because FBs rapidly decrease cell cycle division and proliferative rate after birth, they are prone to phenotypic changes and senescence in cell culture soon after a few passages. Therefore, primary cultures of differentiated fibroblasts from embryos are more desirable. Below we will describe a method that provides good cell yield and viability of E16 CD-1 mouse embryonic cardiac fibroblasts in primary cultures.
