Protocol provides methods for cryofreezing and subsequent thawing of mammalian cells. Pre-confluent cells are trypsinized, pelleted, resuspended in freezing medium, and gradually frozen. When needed, frozen cells are thawed quickly under running tap water and transferred to growth medium. - [Read Cryopreservation of Mammalian Culture Cells: Preparation and Recovery of Samples Protocol]
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]
Describes the steps in detail to isolate and expand neural stem cells in the form of neurospheres from tissue dissections of the post-natal mouse brain. Procedures for the long term passage of neurospheres and the cryopreservation of neurospheres are also provided. In addition to the guidelines and tips for generating neurosphere cultures, we describe the method to prepare neurospheres for analysis by light microscopy. - [Read Neural Stem Cell Culture: Neurosphere Generation, Microscopical Analysis and Cryopreservation]
Cryopreserved PBMCs are a common specimen source for studies of immunological responses to vaccines,
immunotherapies, etc. The health and viability of cells recovered post-cryopreservation are of course
critical to the success and accuracy of immunological assays performed on them. This protocol standardizes PBMC isolation and cryopreservation techniques, specifically for the
assessment of thawed cells by cytokine flow cytometry. - [Read Protocol for Isolation, Cryopreservation, and Thawing of PBMCs]
