Supplementary Material

Supplemental A. Characterization of E16.5 embryonic cardiac cells. (A) Quantification of actively dividing cardiomyocytes in E16.5 embryonic hearts. Smooth muscle (SMA) and endothelial (CD31) components of the cell suspension obtained from E16.5 hearts. Percentage of cells expressing CD31 or SMA in the population derived from E16.5 hearts.

Supplemental B. Movie of beating 16.5 dpc cardiac cells recellularized heart. (A) Beating activity in an embryonic heart scaffold incubated with E16.5 cardiac cells for 20 Hr.

Supplemental C. Agitation decellularization produces a more intact cardiac matrix. (A) Heart decellularized using a perfusion protocol with 0.25% SDS and DNase (0.5 mg/ml) solution. (B) Heart decellularized by agitation in a 0.25% SDS and DNase (0.5 mg/ml) solution. Structure is better preserved after the agitation protocol. Main anatomical components of the heart are labeled.
