Cardiovascular diseases, including myocardial infarction, are the leading cause of death worldwide for both men and women. Current therapies are limited by the restricted intrinsic regeneration capacity of the heart and by the lack of organs for transplant ...
This report demonstrates the feasibility of surface-initiated atom transfer radical polymerization to prepare thin polymer layers ("brushes") that can be functionalized with short peptide ligands and which may be of use as coatings to promote endothelializ ...
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 the domain of regenerative medicine research there are many fronts aimed at increasing our understanding of induced pluripotent, embryonic and adult stem cells. Recently a new front has appeared, stem cell niches, the microenvironment that is a crucial ...
Most tissue engineering approaches include the delivery of reparative cells to a damaged host tissue. Generally these cells are sought to be of a stem cell character since they retain a high potential for proliferation and differentiation into diverse phen ...
Current restrictions for human cell-based therapies have been related to technological limitations with regards to cellular proliferation capacity and maintenance of differentiated phenotype for primary human cell culture. In our experience, we have seen t ...
The ability of the biomimetic peptides YIGSR, PHSRN and RGD to selectively affect adhesion and migration of human microvascular endothelial cells (MVEC) and vascular smooth muscle cells (HVSMC) was evaluated. Cell mobility was quantified by time-lapse vide ...
The formation of scar tissue due to dedifferentiation of smooth muscle cells (SMCs) is one of the major issues faced when engineering bladder tissue. Furthermore, cell sources for regenerating the SMC layer are also limiting. Here we explore if human mesen ...
This unit describes a protocol for the isolation of cells from murine embryonic stem cells with hematopoietic stem cell activity, defined by the ability to reconstitute, long term, multiple lineages of the hematopoietic system of lethally irradiated mice. ...
Embryonic stem (ES) cells represent a unique cellular model to recapitulate in vitro early steps of embryonic development and an unlimited cellular source in therapy for many diseases, as well as targets for drug discovery and toxicology screens. Although ...
