Pluripotent ES cells can develop into many types of differentiated tissues if they are placed back into a differentiating environment. Often, differentiation proceeds through an intermediate stage called the embryoid body (EB). EBs can be manipulated further to generate more differentiated cell types. This protocol describes a method for differentiation of ES cells into EBs. - [Read Differentiating Embryonic Stem (ES) Cells into Embryoid Bodies Protocol]
Insect cell cultures are now commonly used in insect physiology, developmental biology, pathology, and molecular biology. As the field has advanced from methods development to a standard procedure, so has the diversity of scientists using the technique. This paper describes methods that are effective for maintaining various insect cell lines. The procedures are differentiated between loosely or non-attached cell strains, attached cell strains, and strongly adherent cell strains. - [Read Methods for Maintaining Insect Cell Cultures]
