Great Omentum Decellularized Matrixderived from porcine great omentum tissue,is obtained through a process of degreasing and decellularization,and is provided sterile for single-use.Its main components include collagen,glycosaminoglycans,glycoproteins,and trace growth factors,without cellular components.This great omentum decellularized matrix possesses a three-dimensional spatial structure,which can promote cell migration,proliferation,and differentiation,and exhibits excellent tissue repair capabilities.This material has passed National Medical Products Administration Center for Medical Device Evaluation Master File Registration Record (M2022063-000).

Decellularized dermal matrix,derived from porcine dermal tissue,removes cellular components through degreasing and decellularization processes,and preserve the spatial structure of dermal tissue.The decellularized dermal matrix,similar to the structure and main components of human dermal tissue,can promote regeneration and repair of dermal tissue with dermal defects caused by external forces.

Decellularized Tendon Matrix derived from bovine Achilles tendon,is obtained through decellularization,and sterile to provide single-use.Tendon decellularized matrix has low immunogenicity and the composition and spatial structure of natural tendon extracellular matrix,which provides a microenvironment for cell migration,differentiation and proliferation,and promotes regeneration and repair of tendon injuries.

The main components of the submucosa of Small Intestinal Submucosa are typeⅠand Ⅲ collagen fibers,a small number of cells,some larger blood vessels,lymph vessels and nerves.Small Intestinal Submucosa Decellularized Extracellular Matrix obtains through a series of industrial processes such as inactivation,degreasing,decellularization to remove residual cells、DNA、α-gal proteins and other immunogenic substances.

Dermal-epidermal Junction（DEJ）is a type of extracellular matrix that exists in all organs and tissues in the human body and assumes important functions.Located at the interface between the epidermis and the dermis of the skin, it is a wavy reticular structure with a length of about 0.5 μm to 1 μm,which is the interface and transition structure between the two layers. The main components include type IV and VII collagen,laminin,reticulin/nestin,integrins,and others.Through their cross-linking to form a reticular structure,the basement membrane constitutes a rich variety of biological functions, mainly for the epidermal-dermal connections,signaling function and permeability barrier function.

Humanized collagen is a type of collagen produced through bioengineering technology.Based on the genetic sequence of human collagen,it is expressed in microorganisms (such as Escherichia coli) and produced on a large scale through optimization and recombination technology.This collagen has a highly similar or identical structure to human collagen,and therefore doesn’t cause immune rejection when used,and is suitable for various fields such as skin care and medical cosmetology.
