High density mapping analysis of hiPS-CM contractile strain on a noncoated decellularized spinach leaf. (a) Single frame of high speed contraction video of hiPS-CMs on a noncoated decellularized spinach leaf. High density mapping (HDM) strain analysis was performed on contractile hiPS-CM clusters on decellularized leaves, illustrated in red circle. The inset visualizes several cells on the leaf. Scale bar 50 μm. (b) Contractile strain of the hiPS-CM cluster was measured with HDM over time. Peaks in strain plot indicate maximum strain per contraction on the leaf’s surface
