ATCC-BYS0110 Human Induced Pluripotent Stem Cells (iPSCs) were derived from bone marrow CD34+ cells obtained from a healthy African American male donor.
ATCC iPSCs have been adapted to feeder- and serum-free culture conditions.
The base medium for this cell line is Pluripotent Stem Cell SFM XF/FF (ATCC® No. ACS-3002) which is a ready-to-use medium for serum-free and feeder-free iPSC culture.
Cell culture dishes are coated with CellMatrix Basement Membrane Gel (ATCC® No. ACS-3035) to provide a surface for the attachment of iPSCs.
Coating Procedure:
Post thaw day 1, perform a 100% medium change and remove all cells that did not attach. Perform a 100% medium change every day. Passage the cells every 4 to 5 days (80% confluent) at an appropriate split ratio (a 1:4 split ratio is recommended). If the colonies are close to, or touching each other, the culture is overgrown. Overgrowth will result in differentiation.
This protocol is designed to passage stem cell colonies cultured in a 6 cm dish, using Stem Cell Dissociation Reagent (ATCC ACS-3010) to detach the cell colonies. The recommended spilt ratio is 1:4. Volumes should be adjusted according to the size and number of the tissue culture vessels to be processed.
Lyophilized proteins tend to be hygroscopic. Bring the vial of Stem Cell Dissociation Reagent to room temperature before opening. The vial should not be cool to the touch. Once opened, the lyophilized material should be stored desiccated. The specific activity of the reagent is found on the certificate of analysis. Dissolve the appropriate amount of Stem Cell Dissociation Reagent in DMEM: F-12 Medium to prepare a 0.5 U/mL working solution.
Note: Addition of ROCK inhibitor has been shown to increase the survival rate. The use of ROCK inhibitor may cause a transient spindle-like morphology effect on the cells. However, the colony morphology will recover after subsequent media change without ROCK inhibitor.
For optimal results, cryopreserve stem cell colonies when the cell cultures are 80%confluent. This protocol is designed to cryopreserve stem cell colonies cultured in a 6 cm dish.
