Engineering bone tissue from human embryonic stem cells.
In extensive bone defects, tissue damage and hypoxia lead to cell death, resulting in slow and incomplete healing. Human embryonic stem cells (hESC) can give rise to all specialized lineages found in healthy bone and are therefore uniquely suited to aid regeneration of damaged bone. We show that the cultivation of hESC-derived mesenchymal progenitors on 3D osteoconductive scaffolds in bioreacto...
متن کاملEngineering tissue from human embryonic stem cells
Recent advances in human embryonic stem cell (hESC) biology now offer an alternative cell source for tissue engineers, as these cells are capable of proliferating indefinitely and differentiating to many clinically relevant cell types. Novel culture methods capable of exerting spatial and temporal control over the stem cell microenvironment allow for more efficient expansion of hESCs, and signi...
متن کاملEndochondral bone tissue engineering using embryonic stem cells.
Embryonic stem cells can provide an unlimited supply of pluripotent cells for tissue engineering applications. Bone tissue engineering by directly differentiating ES cells (ESCs) into osteoblasts has been unsuccessful so far. Therefore, we investigated an alternative approach, based on the process of endochondral ossification. A cartilage matrix was formed in vitro by mouse ESCs seeded on a sca...
متن کاملEngineering bone tissue substitutes from human induced pluripotent stem cells.
Congenital defects, trauma, and disease can compromise the integrity and functionality of the skeletal system to the extent requiring implantation of bone grafts. Engineering of viable bone substitutes that can be personalized to meet specific clinical needs represents a promising therapeutic alternative. The aim of our study was to evaluate the utility of human-induced pluripotent stem cells (...
متن کاملReprogramming by cytosolic extract of human embryonic stem cells improves dopaminergic differentiation potential of human adipose tissue-derived stem cells
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
