Reports have been published on the identification of tumor cells with stem cells characteristics in different types of tumors (acute myelogenic leukemia, breast cancer, prostate cancer, bone sarcomas, liver cancer, and melanomas). We and other groups have previously reported the isolation of cancer stem cells from adult glioblastoma multiforme. These cells express stem c

Neonatal hypoxic-ischemic encephalopathy: emerging therapeutic strategies based on pathophysiologic phases of the injury.

Neonatal hypoxic ischemic encephalopathy (HIE) is an important cause of neonatal death and disability. At present, there is no unified standard and specialized treatment method for neonatal HIE. In clinical practice, we have found that a gap remains between preclinical medical research and clinical application in the treatment of neonatal HIE. To promote an organic combination of preclinical research and clinical application, we propose the different phases as intervention targets, based on the pathophysiologic changes in phases I, II, and III of neonatal HIE; moreover, we suggest transformati

Therapeutic Potential of Menstrual Blood-Derived Stem Cell Transplantation for Intrauterine Adhesions.

An increasing number of women experience intrauterine adhesion as a result of intrauterine operations, such as induced abortion, which can cause infertility, recurrent abortion and amenorrhea. Although some strategies have been applied clinically, such as hysteroscopy adhesiolysis of intrauterine adhesions, the results have not been promising. As regenerative medicine develops, research on menstrual blood-derived stem cell transplantation is increasing due to the properties of these cells, including self-renewal, differentiation, angiogenesis, anti-inflammation and immunomodulation. As a resul

Stem Cell Therapy for Hypoplastic Left Heart Syndrome: Mechanism, Clinical Application, and Future Directions.

Hypoplastic left heart syndrome is a type of congenital heart disease characterized by underdevelopment of the left ventricle, outflow tract, and aorta. The condition is fatal if aggressive palliative operations are not undertaken, but even after the complete 3-staged surgical palliation, there is significant morbidity because of progressive and ultimately intractable right ventricular failure. For this reason, there is interest in developing novel therapies for the management of right ventricular dysfunction in patients with hypoplastic left heart syndrome. Stem cell therapy may represent one

Establishment of an Immortalized Canine Hippocampal Neural Stem Cell Line via SV40LT Retroviral Transduction.

Dogs represent a promising animal model for analyzing human neurodegenerative diseases, owing to their similarities to humans in nervous system architecture and behavioral phenotypes. Neural stem cells (NSCs) serve as a highly valuable in vitro experimental model for investigating neurogenesis, neurodegenerative disease pathogenesis, and neural molecular biology; however, studies on immortalized canine neural stem cell lines remain scarce. Herein, we successfully established an immortalized canine hippocampal neural stem cell line that can be continuously passaged in vitro via SV40 large T ant

Prospects for osteoprogenitor stem cells in fracture repair and osteoporosis.

PURPOSE OF REVIEW: Bone regeneration and fracture repair are the complex processes of mesenchymal stem cell invasion, chondrogenesis, osteogenesis and angiogenesis. The coordinated actions of these principal processes result in the reconstruction of a normal bone and restoration of a structural unit. However, these normal bone regenerative mechanisms breakdown during fracture repair failure and postmenopausal osteoporosis. RECENT FINDINGS: Recent discoveries of circulating multipotent stem cells with mixed characteristics of endothelial cell and osteogenic capacity have raised interest in new

Development of Organoids from Mouse Pituitary as In Vitro Model to Explore Pituitary Stem Cell Biology.

The pituitary is the master endocrine gland regulating key physiological processes, including body growth, metabolism, sexual maturation, reproduction, and stress response. More than a decade ago, stem cells were identified in the pituitary gland. However, despite the application of transgenic in vivo approaches, their phenotype, biology, and role remain unclear. To tackle this enigma, a new and innovative organoid in vitro model is developed to deeply unravel pituitary stem cell biology. Organoids represent 3D cell structures that, under defined culture conditions, self-develop from a tissue'
