Characteristics |
developmental stage: enriched hESC-CM, day 18 of in vitro differentiation passage number: passage 97 cell line: HES-2 origin of a cell line: ES Cell International, Singapore

Treatment protocol |
Cardiac differentiation of human iPS and ES cells was carried out on the murine visceral endoderm-like cell line END2 as described by Mummery C, et al. Differentiation of human embryonic stem cells to cardiomyocytes: role of coculture with visceral endoderm-like cells. Circulation 107(21):2733-2740, 2003. To initiate co-cultures, human iPS and ES cell colonies were dissociated into clumps by either using collagenase IV (1mg/ml in DMEM/F-12 at 37°C for 5-10 minutes) or by manual cutting. The differentiation was carried out in Knockout-DMEM having 1mM L-glutamine, 1x non-essential amino acids, 0.1 mmol/L beta-mercaptoethanol and Penicillin-Streptomycin (100 U/ml and 100 ug/ml, respectively) but devoid of serum and serum replacement (all reagents were from Invitrogen). Medium change was performed at day 5, 9, 12 and 15 after beginning of the co-culture. Contracting cardiac outgrowths were first observed on day 11 after the initiation of human iPS and ES cell differentiations.

Growth protocol |
The human iPS and ES cells were maintained on irradiated (2x26 Gray/6 minutes each) mouse embryonic fibroblasts (MEFs). MEFs were derived from outbred CF-1 mice and plated at a density of 19500 cells/sqcm in 60 mm tissue culture dishes (BD Falcon). Both lines were maintained in DMEM/ F12 culture medium supplemented with Glutamax, 20% knockout serum replacer, 1% nonessential amino acids and 0.1 mmol/L beta-mercaptoethanol. Additionally, the medium was supplemented with 100 ng/ml basic fibroblast growth factor (Peprotech) for iPS cells, and 4 ng/ml for human ES cells. Culture media were changed daily and undifferentiated cells were passaged by manual dissection of cell clusters every five to six days.
