Abstract
Human induced pluripotent stem cells (hiPSCs) can be efficiently differentiated into cardiomyocytes (CMs), which can be used for cardiac disease modeling, for drug screening, and to regenerate damaged myocardium. Implementation of xeno-free culture systems is essential to fully explore the potential of these cells. However, differentiation using xeno-free adhesion matrices often results in low CM yields and lack of functional CM sheets, capable of enduring additional maturation stages. Here, we established a xeno-free CM differentiation platform using TeSR/Synthemax, including a replating step and integrated with two versatile purification/enrichment metabolic approaches. Results showed that the replating step was essential to reestablish a fully integrated, closely-knit CM sheet. In addition, replating contributed to increase the cTnT expression from 65% to 75% and the output from 2.2 to 3.1 CM per hiPSC, comparable with the efficiency observed when using TeSR/Matrigel. In addition, supplementation with PluriSin1 and Glu-Lac+ medium allowed increasing the CM content over 80% without compromising CM sheet integrity or functionality. Thus, this xeno-free differentiation platform is a reliable and robust method to produce hiPSC-derived CMs, increasing the possibility of using these cells safely for a wide range of applications.

Abstract
![]()
Chemically defined
hydrogels are increasingly utilized to define
the effects of extracellular matrix (ECM) components on cellular fate
determination of human embryonic and induced pluripotent stem cell
(hESC and hiPSCs). In particular, hydrogels cross-linked by orthogonal
click chemistry, including thiol-norbornene photopolymerization and
inverse electron demand Diels–Alder (iEDDA) reactions, are
explored for 3D culture of hESC/hiPSCs owing to the specificity, efficiency,
cytocompatibility, and modularity of the cross-linking reactions.
In this work, we exploited the modularity of thiol-norbornene photopolymerization
to create a biomimetic hydrogel platform for 3D culture and differentiation
of hiPSCs. A cell-adhesive, protease-labile, and cross-linkable gelatin
derivative, gelatin-norbornene (GelNB), was used as the backbone polymer
for constructing hiPSC-laden biomimetic hydrogels. GelNB was further
heparinized via the iEDDA click reaction using tetrazine-modified
heparin (HepTz), creating GelNB-Hep. GelNB or GelNB-Hep was modularly
cross-linked with either inert macromer poly(ethylene glycol)-tetra-thiol
(PEG4SH) or another bioactive macromer-thiolated hyaluronic acid (THA).
The formulations of these hydrogels were modularly tuned to afford
biomimetic matrices with similar elastic moduli but varying bioactive
components, enabling the understanding of each bioactive component
on supporting hiPSC growth and ectodermal, mesodermal, and endodermal
fate commitment under identical soluble differentiation cues.
