ABSTRACT: BACKGROUND: Gut homeostasis is central to whole organism health, and its disruption is associated with a broad range of pathologies. Following damage, complex physiological events are required in the gut to maintain proper homeostasis. Previously ...
Transforming Growth Factor beta (TGFβ) signaling plays an important role in a variety of cellular processes during embryonic development, adult tissue homeostasis and cancer. TGFβI ligand is a potent inhibitor of early hematopoietic progenitor [1] cells in ...
Stem cell use in bladder tissue engineering is a recently addressed area of investigation that has generated excitement as a novel way to restore and regenerate lost or damaged urinary bladder tissue. The remodelling of smooth muscle plays a significant ro ...
Muscle degenerative disorders, such as Duchenne muscular dystrophy, have a profound impact on the quality of life and survival of patients. Transplantation of myoblasts to restore muscle function has been discouraging since these cells die and don't migrat ...
In recent years sophisticated biomaterials have made a significant impact on our understanding of cellular behavior, particularly in the fields of stem cell research and tissue engineering. Nevertheless, the promising potential of stem cells for regenerati ...
Robust and large-scale expansion of umbilical cord blood stem cells in vitro is necessary for widening the usage of transplantation therapies for the treatment of hematological and immune diseases. The lack of understanding of the complex inter-cellular ne ...
The Hedgehog (Hh) signaling pathway is a developmentally conserved regulator of stem cell function. Several reports suggested that Hh signaling is an important regulator of hematopoietic stem cell (HSC) maintenance and differentiation. Here we test this hy ...
Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system. After initiation of the heartbeat in vertebrates, cells lining the ventral aspect of the dorsal aorta, the placental vessels, a ...
Adult stem cells reside in a specialized microenvironment, the niche, which controls their behavior. As mammary stem cells, and consequently their niches, are still poorly defined, we look at better-characterized adult mammalian stem cell niches in the hem ...
The Janus Kinase (JAK) Signal Transducer and Activator of Transcription (STAT) pathway is involved in the regulation of Intestinal Stem Cell (ISC) activity to ensure a continuous renewal of the adult Drosophila midgut. Three ligands, Unpaired1, 2 and 3 are ...
