摘要:
Provided herein is a placental membrane product comprising an immunocompatible amniotic membrane. Such placental membrane products can be cryopreserved and contain therapeutic factors and viable cells after thawing. The placental membrane products are useful in wound healing and tissue repair/regeneration as they are capable of promoting angiogenesis, reducing inflammation, inhibiting proteases and free radical oxidation, reducing scar formation, and other methods that promote healing. The present technology relates to products to protect injured or damaged tissue, or as a covering to prevent adhesions, to exclude bacteria, to inhibit bacterial activity, and/or to promote healing or growth of tissue. The field also relates to methods of manufacturing and methods of use of such membrane-derived products.
摘要:
Provided herein is a bone repair composition that is composed of periosteum containing an angiogenic growth factor(s), cancellous bone chips containing viable osteogenic cells, and, optionally, demineralized bone matrix (DBM) chips. Also provided herein are articles of manufacture and use of the compositions and methods of use of the compositions to treat bone defects.
摘要:
Disclosed are methods of lyophilizing a tissue sample comprising obtaining a tissue sample, contacting the tissue sample with a lyoprotectant solution, freezing the tissue sample, performing a first drying step of the tissue sample after freezing, and performing a second drying step of the tissue sample after the first drying step. Disclosed are lyophilized tissues prepared using the disclosed methods of lyophilizing a tissue sample comprising obtaining a tissue sample, contacting the tissue sample with a lyoprotectant solution, freezing the tissue sample, performing a first drying step of the tissue sample after freezing, and performing a second drying step of the tissue sample after the first drying step. Disclosed are methods of treating a wound or tissue defect comprising administering a reconstituted lyophilized tissue to the wound or tissue defect.
摘要:
This invention provides porated cartilage products and methods of producing porated cartilage products. Optionally, the cartilage products are sized, porated, and digested to provide a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.
摘要:
Provided herein is a placental product comprising an immunocompatible amniotic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.

Provided herein is a placental product comprising an immunocompatible chorionic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.
摘要:
Disclosed are compositions comprising a non-homogenized chorionic matrix, a homogenized amniotic matrix and a homogenized UC (UC) matrix, wherein the non- homogenized chorionic matrix comprises viable cells. Disclosed are methods of making the compositions disclosed herein comprising preparing a non-homogenized chorionic matrix, preparing a homogenized amniotic matrix, preparing a homogenized UC matrix, and combining the non-homogenized chorionic matrix, the non-homogenized chorionic matrix, and the homogenized UC matrix. Disclosed are methods of treating a tissue injury or chronic pain comprising administering any of the disclosed compositions to an area of a subject comprising a tissue injury.
摘要:
This invention provides disrupted cartilage products, methods of manufacturing disrupted cartilage products, and methods of treating a subject comprising administering a cartilage product. The cartilage products are manufactured by a method comprising disrupting a collagen matrix, e.g. to produce a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.

摘要:
A sealable tray system for sealing a product in a transport-ready position. The sealable tray system has an insert, a first lid, an outer basin, and a second lid. The insert has a well portion with a base surface that extends upwardly to support the product. The insert also has a flange portion that extends outwardly from the well portion and is sealingly engaged by the first lid. The outer basin receives the insert in the transport-ready position, and the second lid engages a top surface of the outer basin. Methods of sealing a product in a transport-ready position are also disclosed.
