A scaffold comprising an aligned fiber. Further, a scaffold comprising one or more electrospun fibers wherein a fast Fourier transform (FFT) analysis result of the fibers have adjacent major peaks with about 180° apart from each other. Also, methods for promoting differentiation of stem cells into osteoblasts, chondrocytes, ligament or tendon, the method comprising culturing the cells on the scaffold or aligned fiber in conditions suitable for the cell differentiation.

The present disclosure relates to compositions and methods for modulating wound healing and regeneration. More particularly, the present disclosure relates to immunomodulatory agents that promote wound healing and tissue regeneration, and that may be optionally used in combination with synthetic or bio-material scaffolds.

The present disclosure provides methods for restoring reproductive health and/or fertility in a subject by delivering immature follicles to the subject using an ovarian-derived hydrogel. The present disclosure also provides methods for treating ovarian-associated diseases using ovarian-derived hydrogels or their derivatives for delivery of therapeutic agents to the subject in need thereof. The present disclosure further provides kits for restoring reproductive health and/or fertility, and kits for treating ovarian-associated diseases.

Cardiovascular prostheses that include an ECM-mimicking composition, which is adapted to induce modulated healing of damaged or diseased cardiovascular tissue and, thereby, associated structures, when administered thereto. The ECM-mimicking composition includes a polymer component and a pharmacological component. The polymer component includes poly(glycerol sebacate) (PGS). The pharmacological component includes a corticosteroid. The ECM-mimicking composition can also include a biological component having a biologically active agent, such as an exosome, a cytokine and a growth factor.

The growth factor profile, connective tissue matrix constituents, and immunoprivileged status of urodele extracellular matrix (ECM) and accompanying cutaneous tissue, plus the presence of antimicrobial peptides there, render urodele-derived tissue an ideal source for biological scaffolds for xenotransplantation. In particular, a biological scaffold biomaterial can be obtained by a process that entails (A) obtaining a tissue sample from a urodele, where the tissue comprises ECM, inclusive of the basement membrane, and (B) subjecting the tissue sample to a decellularization process that maintains the structural and functional integrity of the extracellular matrix, by virtue of retaining its fibrous and on-fibrous proteins, glycoaminoglycans (GAGs) and proteoglycans, while removing sufficient cellular components of the sample to reduce or eliminate antigenicity and immunogenicity for xenograft purposes. The resultant urodele-derived biomaterial can be used to enhance restoration of skin homeostasis, to reduce the severity, durations and associated damage caused by post-surgical inflammation, and to promote progression of natural healing and regeneration processes. In addition, the biomaterial promotes the formation of remodeled tissue that is comparable in quality, function, and compliance to undamaged human tissue.

Methods of decellularization of tissue, such as mammalian tissue, are provided, along with methods of making an extracellular matrix (ECM) preparation. Systems and apparatus useful in performing the methods are also provided.

The present disclosure provides medical products including an adhesive containing a carboxyalkyl cellulose and sorbitol. Such medical products can find use as a bolster material for use in conjunction with a surgical fastening device such as a stapler. Such adhesives may include advantageous properties such as the ability to retain tack while stored under a peelable cover. Related methods of manufacture and use are also described.

Tissue prostheses having a base structure and a physiological sensor system. The tissue prostheses are adapted and configured to induce remodeling of damaged tissue and regeneration of new tissue and concurrently detect and monitor physiological characteristics when implanted in the subject.

Graft materials and devices for surgical breast procedures, as well as methods of making graft devices, are described.

Provided is a tissue gel for transplantation and a method of preparing the same, including: a process (a) of preparing a composition containing a decellularized extracellular matrix; a process (b) of maintaining a tensile state by applying a tensile force to a stretching device made of an elastic polymer material; and a process (c) of injecting the composition prepared in the process (a) into the stretching device maintained in the tensile state in the process (b), allowing the composition to crosslink, and then removing the tensile force to align fibrils in the decellularized extracellular matrix in one direction.
