A method of treating a spinal cord injury in a subject in need thereof is disclosed. The method comprises implanting a scaffold into the spinal cord of a subject, wherein the scaffold is seeded with oral mucosa stem cells (OMSC) and/or cells that have been ex vivo differentiated from said OMSCs, thereby treating the spinal cord injury.

Described herein are compositions and methods related to derivation of human notochordal cells differentiated from induced pluripotent stem cells (iPSCs). The inventors have developed a two-step process for generating these iPSC-derived notochordal cells (iNCs), which can provide a renewable source of therapeutic material for use in degenerative disc disease (DDD). As iNCs are capable of reversing DDD and supporting regeneration of intervertebral disc (IVD) tissue based on the understanding that NC cells maintain homeostasis and repair of other IVD cell types such as nuclear pulposus (NP).

In various aspects and embodiments, the present invention provides methods for maintaining motor neuron health in the spinal cord and pro-regenerative capacity of a proximal nerve segment subsequent to a nerve injury in a subject in need thereof, the methods comprising transplanting a stretch-grown tissue engineered nerve graft (TENG) into a proximal site contacting the proximal nerve segment.

The present invention relates to a method for preparing of a nerve conduit using bio-printing technology and a nerve conduit prepared by the same, and it can easily prepare a nerve conduit by simulating a nerve bundle and nerve tissue, and the like, by three-dimensionally printing bio-ink comprising a neuronal regeneration material on one side of a porous polymer scaffold.

The disclosure provides a biological brain-computer interface comprising genetically modified cells engrafted onto an adult mammal (e.g., mouse) above cortical layer 1, forming an artificial cortical layer termed layer zero (L0). Following engraftment, L0 goes through a developmental process characterized by synchronous waves of activity that gradually recede to resemble spontaneous cortical activity. Axons and dendrites from L0 nondestructively infiltrated the host cortex and formed synaptic connections necessary for bidirectional communication with the brain.

A material for inducing nerve regeneration in a transplantation site, or a material for recovering the function of nerve tissues in a transplantation site, the material comprising a cell structure having a thickness of at least 300 μm that is constructed by stacking the spheroids of bone marrow-derived cells, adipose tissue-derived cells, dental pulp-derived cells, amnion-derived cells, placenta-derived cells, umbilical cord-derived cells, or umbilical cord blood-derived cells, on a needle-shaped body arranged on a substrate.

The present invention provides novel compositions comprising multipotent cells or microvascular tissue, wherein the cells or tissue has been sterilized and/or treated to inactivated viruses, and related methods of using these compositions to treat or prevent tissue injury or disease in an allogeneic subject.

The invention relates to a cell sheet construct for neurovascular reconstruction. The cell sheet construct has a vascular endothelial cell layer and a neural stem cell layer, and the two layers are physically in direct contact with each other, where the vascular endothelial cell layer forms branching vasculatures, and the neural stem cell layer differentiates into neurons. The invention also relates to a method for manufacturing the cell sheet construct, having the following steps: culturing vascular endothelial cells on a substrate to form a vascular endothelial cell layer, seeding neural stem cells on the vascular endothelial cell layer to make the neural stem cells be physically in direct contact with the vascular endothelial cell layer, and culturing the neural stem cells and the vascular endothelial cell layer to differentiate into neurons and branching vasculatures to form a cell sheet construct.

A scaffold-free nerve conduit and a method of making the scaffold-free nerve conduit are provided. A nerve-repair method using the scaffold-free nerve conduit also is provided.
