Brief Summary
|
This
study proposes to investigate the transplantation of ex-vivo cultivated
allogenic limbal stromal stem cells for the treatment of the corneal
pathologies after alginate encapsulation. The limbus is an ideal source as the stem cells are numerous and
located very superficially in the tissue (17). Pre-clinical work
suggests human corneal stromal stem cells can be isolated from the cadaveric
tissues, cultivated in conditions suitable for cell based therapy and used to
prevent fibrosis in a murine model of corneal stromal scarring. Further, these
cells are able to successfully engraft, differentiate, and mediate wound
healing in the corneal stroma such that the tissue remains healthy, free of
fibrotic tissue, and optically transparent. The clinical implications of these
findings are substantial in that it represents the potential to lessen the
burden on donor tissue necessary for corneal allografts by using cultured cells
to regenerate tissue. We foresee the ability of a clinician to and grow and
expand the cells in number and after surgically removing the scar tissue from
the wounded eye, apply the cultured limbal stromal stem cells to regenerate
healthy, transparent tissue. |
