This video protocol provides step-by-step instructions on how to consistently perform the Colony Forming Cell (CFC) Assay. Tips are provided throughout the video to help optimize the assay procedure, including tricks to accurately evaluate and score colony formations.
This protocol must be read in its entirety before using Catalog # NSC001.Caution: The rat cortical stem cells used in this protocol contain trace amounts of human transferrin and DMSO, and the media used in this protocol contains trace amounts of transferrin. The transferrin was purified from donor plasma and tested at the donor level using an FDA licensed method and found to be non-reactive for anti HIV-1/2 and Hepatitis B surface antigen.
Antibodies including anti-mouse CD5, CD11b, CD45R (B220), Ly-6G (Gr-1), and TER-119 can be used to efficiently tag bone marrow-derived cells committed to major hematopoietic lineages, including T lymphocytes, B lymphocytes, monocytes/macrophages, granulocytes, and erythrocytes. These antibodies can be used in conjunction with magnetic particle separation systems or flow cytometric cell sorting to deplete lineage-committed cells and enrich for uncommitted hematopoietic progenitors.
Ex vivo expanded neural stem cells serve as excellent tools for researchers studying neural development and neurological disorders. Ready-to-use primary cortical stem cells, isolated from E14.5 Sprague-Dawley rats (Catalog # NSC001), can be grown in monolayer, as described here, or as neurospheres. These cells retain capacity for multi-lineage differentiation into astrocytes, neurons, and oligodendrocytes.

This protocol is designed for BG01V human embryonic stem (hES) cells grown in Mouse Embryonic Fibroblast (MEF) Conditioned Media (Catalog # AR005). If using different cell lines or growth media, the protocol below may need to be modified.
The quality of the human pluripotent cells used in the differentiation is critical. Use of suboptimal quality or very high passage pluripotent cells can result in decreased differentiation efficiency and/or increased cell death.

Mesenchymal stem cells (MSCs) are functionally defined by their capacity to self renew and their ability to differentiate into multiple cell types including adipocytes, chondrocytes and osteocytes. This protocol describes the chondrogenic differentiation of MSCs using the StemXVivoTM Human/Mouse Chondrogenic Base Media (Catalog # CCM005) and StemXVivo Human/Mouse Chondrogenic Supplement (Catalog # CCM006).
The colony forming cell (CFC) assay, also referred to as the methylcellulose assay, is an in vitro assay used in the study of hematopoietic stem cells. The assay is based on the ability of hematopoietic progenitors to proliferate and differentiate into colonies in a semi-solid media in response to cytokine stimulation. The colonies formed can be enumerated and characterized according to their unique morphology.

Mesenchymal stem cells (MSCs) are functionally defined by their capacity to self renew and their ability to differentiate into multiple cell types including adipocytes, chondrocytes, and osteocytes (1, 2). MSCs are phenotypically characterized as CD105+, CD90+, CD73+, CD44+, CD34-, CD45-, and CD11b- cells.
Mesenchymal stem cells (MSCs) are functionally defined by their capacity to self renew and their ability to differentiate into multiple cell types including adipocytes, chondrocytes, and osteocytes. This protocol describes the adipogenic differentiation of human and mouse MSCs using the StemXVivo™ Human/Mouse Osteogenic/Adipogenic Base Media (Catalog # CCM007) and StemXVivo Adipogenic Supplement (Catalog # CCM011).
