Project description:In vivo generation of post-infarct human cardiac muscle by laminin-promoted cardiovascular progenitors
| PRJNA392876 | ENA
Project description:This SuperSeries is composed of the SubSeries listed below and contains: bulk RNA-seq of two time series of a xeno-free human cardiomyocyte differentiation protocol starting from HS1001 and H1 hECSs until day 94 cardiomyocytes, single cell sequencing of cardiovascular progenitors (H1 and HS1001-derived cardiovascular progenitors at day 9 and 11) and bulk RNA-Seq of H1 hECSs that have been transferred to a LN-221 matrix. Regeneration of injured human heart muscle is limited and an unmet clinical need. There are no methods for the reproducible generation of clinical quality stem-cell-derived cardiovascular progenitors (CVPs). We identified laminin-221 (LN-221) as the most likely expressed cardiac laminin. We produced it as human recombinant protein, and showed that LN-221 promotes differentiation of pluripotent hESCs towards cardiomyocyte lineage and downregulates pluripotency and teratoma associated genes. We developed a chemically defined, xeno-free laminin-based differentiation protocol to generate CVPs. We show high reproducibility of the differentiation protocol using time-course bulk RNA sequencing developed from different hESC lines. Single-cell RNA sequencing of CVPs derived from hESC lines supported reproducibility and identified three main progenitor subpopulations. These CVPs were transplanted into myocardial infarction mice, where heart function was measured by echocardiogram and human heart muscle bundle formation was identified histologically. This method may provide clinical quality cells for use in regenerative cardiology.

Project description:In this study we show, for the first time, that whole islets can be cultured and significantly expanded long-term in vitro on specific basement membrane (BM) laminin LN-521 which is a normal component of islet BMs. Isolated islets adhere and flatten to form 2-3 cell layer entities with ~10 % of all endocrine cell types proliferating after 2-5 weeks in culture. Time-lapse imaging of freshly isolated islets in suspension labeled with hypoxia and DNA degradation indicators reveals that spherical islets on LN-111 rapidly develop hypoxia and central necrosis, in contrast to islets attached to LN-521, which normal b-cell glucose responsiveness. RNA sequencing analyses reveal that freshly isolated islets express LN-521 binding integrins. Compared to other matrices, islets grown on LN-521 develop a unique expression signature, including expression of specific integrins, involved in cell adhesion and matrix production as well as proliferation. The results reveal specific LN-521-mediated effects into islet cells and suggest that use of in vitro expanded islets may significantly enhance the efficacy of islet transplantation treatment of T1D.

Project description:Stem cell-derived products could replace damaged heart muscle in regenerative cardiology. Here, human embryonic stem cells (hESCs) were differentiated on laminin 521+221 to cardiovascular progenitors (CVPs). The CVPs were transplanted into the infarcted region of 10 pigs and maintained for 4- and 12- weeks. Immunohistology analyses revealed in vivo engraftment and maturation of the CVPs into cardiomyocytes (CMs). Furthermore, heart function was analyzed by magnetic resonance imaging (MRI). We observed significant improvement in the left ventricular ejection fraction (DLVEF: 21.9 ± 1.6 %, at 12-weeks), ventricular wall thickness and wall motion, as well as a reduction in infarction size after CVP transplantation as compared to control pigs (p-value < 0.05). There are temporary episodes of ventricular tachyarrhythmia (VT) in four pigs and one pig had persistent VT. On the other hand, the remaining 5 pigs remained in normal sinus rhythm. Importantly, all pigs survived without any VT-related death, suggesting the potential for developing CVPs towards applications in regenerative cardiology.
