The present disclosure provides a microfluidic device for simulating a blood-brain barrier and a blood-brain barrier simulation system including the same, and the microfluidic device includes: a first channel; a second channel which is adjacently connected to the first channel through one or more microholes and configured to culture neural stem cells; and a chamber which is connected to both ends of the first channel and contains a culture medium.

Methods of tissue engineering, and more particularly methods and compositions for generating various vascularized 3D tissues, such as 3D vascularized embryoid bodies and organoids are described. Certain embodiments relate to a method of generating functional human tissue, the method comprising embedding an embryoid body or organoid in a tissue construct comprising a first vascular network and a second vascular network, each vascular network comprising one or more interconnected vascular channels; exposing the embryoid body or organoid to one or more biological agents, a biological agent gradient, a pressure, and/or an oxygen tension gradient, thereby inducing angiogenesis of capillary vessels to and/or from the embryoid body or organoid; and vascularizing the embryoid body or organoid, the capillary vessels connecting the first vascular network to the second vascular network, thereby creating a single vascular network and a perfusable tissue structure.

The present invention relates, in part, to blood-brain barrier-like tissues that comprise engineered E40RF1+ endothelial cells, and to various compositions and methods useful for making and using such blood-brain barrier-like tissues—both in vitro and in vivo.

A primary culture method in which cells contained in a tissue collected from a living body are primary cultured in vitro, in which the cells in the tissue collected from the living body are seeded and cultured on a top surface of a cell structure containing cells constituting a stroma and composed of a single layer or two or more cell layers laminated in the thickness direction.

The present invention relates to methods for preparing in vitro models of nonalcoholic steatohepatitis.

Described are three-dimensional, engineered, biological breast tissues, adipose tissues, and tumor models, including breast cancer models.

The invention provides a method to prepare a graft comprising a recellularized extracellular matrix of a mammalian liver, liver lobe or portion thereof, and a method of using the recellularized extracellular matrix of a mammalian liver, liver lobe or portion thereof.

This disclosure provides improved method, kits, and systems and for isolating and enriching spermatogonial stem cells (SSCs) from livestock animal testicular tissue. In one aspect, the disclosure provides a method for enriching SSCs from a population of testis-derived cells containing at least one SSC, where the method comprises contacting the population of testis-derived cells to a culture media comprising, or that is preconditioned with, endothelial feeder cells, and maintaining culture conditions suitable for SSC cell maintenance and enrichment. In some embodiments, the media and culture conditions comprise one or more growth factors selected from GDNF, FGF2, SDF-1a, CSF-1, FDGF, NGF, and TGF-β, in any combination. In exemplary embodiments, the SSCs are porcine or bovine SSCs.

The method for the in vitro or ex vivo amplification of stem cells of brown or beige adipocytes includes: extracting (i) a stromal vascular fraction from human adipose tissue including endothelial cells of the vascular network of human adipose tissue and stem cells of brown or beige human adipose tissue and (ii) an extracellular matrix of the human adipose tissue, the extracellular matrix including endothelial cells of the vascular network of human adipose tissue, stem cells of brown or beige human adipose tissue and collagen; mixing the stromal vascular fraction and the extracellular matrix; and culturing the mixture obtained, in suspension, in a culture medium.

The present disclosure relates to a microfluidic devices and methods for culturing bone marrow cells. Aspects include methods of preparing microfluidic devices and culturing bone marrow cells with the microfluidic devices. In some aspects, a method includes providing a microfluidic device having an upper chamber, a lower chamber, and a porous membrane separating the upper chamber from the lower chamber. The method further includes seeding walls of the lower chamber and a bottom surface of the membrane with endothelial cells. The method further includes providing a matrix within the upper chamber. The matrix includes fibrin gel and bone marrow cells. The method further includes filling or perfusing the upper chamber with a media.
