Disclosed are trilaminate collagen-based tissue scaffolds that exhibit remarkable morphological mimicry to that of the natural mammalian periosteum tissue they are useful in remodeling. In particular embodiments, periosteum-modeling trizonal membranes for reforming and regrowing human bone tissue are provided that are composed of a first zone of compact collagen, a second layer of collagen-elastin, and a third layer of biomineralized collagen.

Provided is a means effective in bone regeneration or bone augmentation. Provided is a porous composite containing octacalcium phosphate and parathyroid hormone.

The invention relates generally to generation of biomimetic scaffolds for bone tissue engineering and, more particularly, to multi-level lamellar structures having rotated or alternated plywood designs to mimic natural bone tissue. The invention also includes methods of preparing and applying the scaffolds to treat bone tissue defects. The biomimetic scaffold includes a lamellar structure having multiple lamellae and each lamella has a plurality of layers stacked parallel to one another. The lamellae and/or the plurality of layers is rotated at varying angles based on the design parameters from specific tissue structural imaging data of natural bone tissue, to achieve an overall trend in orientation to mimic the rotated lamellar plywood structure of the naturally occurring bone tissue.

Provided herein are bone marrow stem cell compositions and implants and methods of making and using the same.

The disclosure provides implants containing a plurality of particles containing at least one population of viable cells adherent to and resident in soft tissue matrix or at least one viable population of cells caused to be in contact with the soft tissue matrix; methods of fabricating the implants; and use of the implants in tissue repair.

Disclosed herein is a technology for healing bone defects using bioactive silicate glass (BSG) and a 3D osteomimetic composite porous scaffold containing microspheres comprised of poly(lactide-co-glycolide) (PLGA).

The present disclosure describes methods of treating an injury in a subject using placental tissue streamers, engineered tissue placental tissue hybrids, suture placental tissue hybrids, placental tissue patch hybrids, and tissue hybrids, and the use of these compositions to repair, treat, or support an injury or degenerative process in a subject.

Provided in this disclosure are various composite grafts having a trabecular scaffold with voids defined in at least a portion of the scaffold and a biological component positioned in at least some of the voids of the scaffold. The grafts may have a synthetic scaffold or a bone substrate scaffold. The grafts may be osteogenic, chondrogenic, osteochondrogenic, or vulnerary in nature. Also provided are methods of using the composite grafts to treat a tissue defect in a subject. Methods of manufacturing are also provided. Synthetic scaffolds are manufactured by additive manufacturing. Agitation is used to combine the biological component with the scaffold of the graft.

The present disclosure describes methods of treating an injury in a subject using placental tissue streamers, engineered tissue placental tissue hybrids, suture placental tissue hybrids, placental tissue patch hybrids, and tissue hybrids, and the use of these compositions to repair, treat, or support an injury or degenerative process in a subject.

An elastomeric nanocomposite hydrogel includes first natural polymer macromers covalently crosslinked with second natural polymer macromer and physically crosslinked with a plurality of inorganic nanoparticles. The elastomeric nanocomposite hydrogel is cytocompatible, and, upon degradation, produce substantially non-toxic products.
