Establishment of an induced pluripotent stem cell (iPSC) line (INNDSUi004-A) from a patient with Congenital Nemaline Myopathy.

We used a non-integrated reprogramming approach to establish a human induced pluripotent stem cell (hiPSC) line (INNDSUi004-A) from the skin fibroblasts of a 13-year-old female individual with Congenital Nemaline Myopath. The cells obtained have typical characteristics of embryonic stem cells, show expression of specific pluripotency markers, and can differentiate into three germ layers in vitro. This iPSC cell line has the genetic information of the patient and is a good model for studying disease mechanisms and developing novel therapies.

Establishment of an induced pluripotent stem cell (iPSC) line (INNDSUi005-A) from a healthy female Chinese Han.

We obtained skin fibroblasts from a 34-year-old healthy woman and established a human induced pluripotent stem cell (hiPSC) line (INDSUi005-A) using a non-integrated reprogramming approach. The obtained cells have typical characteristics of embryonic stem cells, can express specific pluripotency markers and have the ability to differentiate into three germ layers in vitro. This iPSC cell line can be used as an in vitro model for studying disease mechanisms and developing novel therapies.

Advances in the differentiation of pluripotent stem cells into vascular cells.

Blood vessels constitute a closed pipe system distributed throughout the body, transporting blood from the heart to other organs and delivering metabolic waste products back to the lungs and kidneys. Changes in blood vessels are related to many disorders like stroke, myocardial infarction, aneurysm, and diabetes, which are important causes of death worldwide. Translational research for new approaches to disease modeling and effective treatment is needed due to the huge socio-economic burden on healthcare systems. Although mice or rats have been widely used, applying data from animal studies to human-specific vascular physiology and pathology is difficult. The rise of induced pluripotent stem cells (iPSCs) provides a reliable in vitro resource for disease modeling, regenerative medicine, and drug discovery because they carry all human genetic information and have the ability to directionally differentiate into any type of human cells. This review summarizes the latest progress from the establishment of iPSCs, the strategies for differentiating iPSCs into vascular cells, and the in vivo transplantation of these vascular derivatives. It also introduces the application of these technologies in disease modeling, drug screening, and regenerative medicine. Additionally, the application of high-tech tools, such as omics analysis and high-throughput sequencing, in this field is reviewed.
