Накратко на български

Сърдечните тъкани, създадени от човешки стволови клетки, се изследват, за да се разбере защо клетките в тях остават незрели. Това е важно за подобряване на технологиите за възстановяване на сърдечната функция при пациенти с cardiovascular заболявания.

CaMKII over stimulation in engineered heart tissues (EHTs) made from human induced pluripotent stem cells (hiPSCs): a parameter involved in the immaturity of hiPSC EHTs cardiomyocytes?

In Europe, as observed in other parts of the world, cardiovascular diseases represent the leading cause of death. The engineering of 3 dimensions (3D) heart tissues (EHTs) technology may represent a promising technique to treat pathologies characterised by a decrease/loss of cardiac function. Taking advantage of the recent availability of human induced pluripotent stem cells (hiPSCs), our laboratory developed a protocol to produce contractile human cardiac tissue (hEHT) from hiPSC-differentiated cardiomyocytes (CMs) (Breckwoldt et al., 2017). If their use is source of hope for numerous applications among which patient cardiac repair, and despite the major advances in EHT technology, CMs still do not acquire a fully mature phenotype. The objective of the project was focused on EHT technology improvement, with particular attention to improving the degree of maturation of CMs (see image attached to the summary).

Цел на проекта

In Europe, as observed in other parts of the world, cardiovascular (CV) diseases represent the leading cause of death. In the European Union, CV deaths account for 1.9 million deaths per year, and treatment costs for CV disease amount to an estimated 200 billion Euros per year. CV diseases encompass various pathologies that can lead to a progressive loss of cardiac contractile function and the clinical syndrome of heart failure (HF), including ischemic heart disease and myocardial infarction. Drug therapy can successfully slow down the progression of HF and reduce mortality, but it cannot revert the loss of myocardium and thus provide no curative approach.The engineering of 3D heart tissues (EHTs) has been developed in 1994 and, in combination with the recent availability of human induced pluripotent stem cells (hiPSCs), may represent a novel, promising technique to treat such cardiac pathologies. EHTs are artificial living and functional 3D heart tissues that could replace injured or malformed heart and restore normal cardiac function on the one hand, and help modeling cardiac diseases and testing drugs in a human heart context on the other hand. However, despite the last years progress and clear advantages compared to 2D cultured hiPSC-cardiomyocytes (CM), EHT-CMs do not reach a fully mature phenotype matching that of isolated CMs from the adult human heart.Based on preliminary results obtained in the host laboratory, a set of indices suggest a role of CaMKII in the EHT-CMs maturation process. The objective of this proposal is thus to determine whether and, if yes, to which extent different CaMKII isoforms are involved in EHT-CM maturation. The EHT-CaMKII project could have very interesting impact on the EHT-CM maturation enhancement and, consequently, on numerous EHT applications encompassing cardiac repair, drug screening or disease modeling. In addition, it will contribute to understanding the biological role of CaMKII in CM biology.
