Lamellar Corneal Autologous Or Homologous Graft In Refractive Surgery
A method of lamellar corneal graft implantation is disclosed herein. In one or more embodiments, the method includes the steps of: (i) modifying a genetic component of a lamellar cornea or other tissue of an animal so that the lamellar cornea or other tissue of the animal can be used for human transplantation; (ii) decellularizing the lamellar cornea or other tissue ex vivo using chemical means; (iii) modifying a shape of the lamellar cornea or other tissue before or after transplantation; and (iv) applying a photosensitizer and ultraviolet radiation to the lamellar cornea or other tissue so as to crosslink collagen and intercellular proteins of the lamellar cornea or other tissue, kill the cells exposed to the photosensitizer, and eliminate an immune response by a host to the implanted lamellar cornea or the tissue.
Ablatable Corneal Inlay For Correction Of Refractive Errors And/Or Presbyopia
An ablatable corneal inlay for correction of refractive errors and/or presbyopia, and a method of correcting refractive errors and presbyopia in an eye of a patient using an ablatable corneal inlay is disclosed herein.
Nonwoven Fabric Containing Silk Fibers, Wound Dressing, iPS Cell Scaffold Material, Nonwoven Fabric for Blood-Compatible Material, Blood-Compatible Material, Production Method of Nonwoven Fabric Containing Silk Fibers, Production Method of Wound Dressing, Production Method of iPS Cell Scaffold Material, Production Method of Non-Woven Fabric for Blood-Compatible Material, and Production Method of Blood-Compatible Material
One embodiment of the present invention provides a nonwoven fabric containing silk fibers in which an abs intensity ratio [abs (1650)/abs (1620)], which is a ratio of an intensity of a peak positioned in a vicinity of 1650 cm.sup.−1 [abs (1650)] in an infrared absorption spectrum to an intensity of a peak positioned in a vicinity of 1620 cm.sup.−1 [abs (1620)] in an infrared absorption spectrum, is larger than 0.65 and 1.90 or less, and a method for producing the nonwoven fabric containing silk fibers.
COMPOSITIONS AND METHODS FOR GENERATING INSULIN-PRODUCING BETA CELLS
Compositions and methods for generating insulin-producing beta cells from pluripotent stem cells are provided. The compositions and methods of the present invention involve stepwise differentiation while the differentiating cells are cultured on a lung tissue-derived acellular scaffold.
VIRAL INACTIVATION METHOD, METHOD FOR PRODUCING DRIED AMNION, AND DRIED AMNION
An object is to develop technology for viral inactivation. As means for resolution, viruses are inactivated by irradiating various articles with microwaves.
CELL TRANSPLANTATION PRETREATMENT METHOD, CELL TRANSPLANTATION PRETREATMENT DEVICE, AND CELL TRANSPLANTATION PRETREATMENT UNIT
A cell transplantation pretreatment method, a cell transplantation pretreatment device, and a cell transplantation pretreatment unit are provided, which are capable of improving the efficiency of loading grafts into a transplantation device. The cell transplantation pretreatment method includes the steps of: transporting a cell group cultured in a culture recess to a pretreatment recess using a culture tray including a plurality of the culture recesses arranged according to a first arrangement, a pretreatment tray including a plurality of the pretreatment recesses arranged according to a second arrangement, and a transplantation device including a needle shaped portion having a tubular shape configured to allow entry and exit of a graft containing the cell group, the transplantation device including a plurality of the needle shaped portions arranged according to the second arrangement; and loading the cell groups simultaneously from the plurality of pretreatment recesses into the plurality of needle shaped portions.
Acellular soft tissue-derived matrices and methods for preparing same
Compositions including a first soft tissue-derived matrix and a second soft tissue-derived matrix are provided, as well as methods of making such compositions. In some embodiments, the composition comprises dilapidated, decellularized adipose tissue-derived matrix and dilapidated, decellularized fascial tissue-derived matrix, which may be combined in various proportions. Such adipose-fascia matrix compositions provide improved volume retention when implanted into a patient. The composition may further include exogenous cells or other substances, and/or a carrier. The composition is suitable for use in plastic surgery procedures, including reconstructive or cosmetic surgery procedures, as well as procedures for wound treatment and tissue regeneration. The methods for making the compositions may involve separation of first and second soft tissues from one another, followed by performing one or more treatments on the separated soft tissues, then combining the treated soft tissues and, optionally, performing one or more additional treatments on the combined soft tissues.
CORNEAL TISSUE
The invention provides an isolated dehydrated corneal tissue, comprising a full thickness corneal stroma, and substantially all, or all, of the Bowman's membrane, wherein the stroma contains cellular material. Also provided is a method to product the tissue and uses of the tissue.
Cultivated Autologous Limbal Epithelial Cell (CALEC) Transplantation
Provided herein are methods for generating cultivated autologous limbal epithelial cell grafts for the treatment of various disorders caused by limbal stem cell deficiency. This invention relates to methods and compositions for treating ophthalmic disorders, diseases and injuries. In particular, the field of the invention is directed to methods, kits and compositions for treating disorders, diseases, defects and injuries of the cornea and ocular surface. The present disclosure relates to preparations of cultured mammalian limbal stem cells, derived from corneal limbus tissue.
