Abstract: An apparatus (e.g., for cell culture for in vitro growth of tissues and/or organs) includes a base, a plate on the base, and a removable barrier component on the plate. The removable barrier component is configured to at least partially define a first region. The removable barrier component includes a bottom surface and a top surface. The bottom surface configured to be in contact with the plate. The top surface is opposite the bottom surface. The press is configured to engage the top surface of the removable barrier component to apply a predetermined pressure to the removable barrier component. The removable barrier component is between the press and the plate. A joint between the plate and the removable barrier component may be substantially impermeable to live cells. The apparatus may further include a removable cover that engages the base to enclose the plate, the removable barrier component, and the press.

Abstract: Provided are biocompatible and implantable scaffolds for treating a tissue defect, such as a bone gap. The scaffolds can have a modular design comprising a tissue scaffold rack designed to accommodate one or more modules. Also provided are methods for fabrication and use of such scaffolds.

Abstract: The present disclosure provides, in various aspects, a method of forming a prefabricated innervated pre-vascularized pre-laminated (PIPP) flap having a stoma or lumen. The method includes providing a cell construct including skin cells and/or mucosa cells. The method further includes forming an integrated in vivo composite at a donor site by grafting the cell construct onto a muscle. The method further includes stabilizing the composite on an obturator component. The method further includes developing a microvascular system in the composite by retaining it in vivo at the donor site for a predetermined period of time. The method further includes removing the obturator component from the stoma or lumen. In certain aspects, the present disclosure also provides a method of restoring a defect including damaged or surgically removed soft tissue using a PIPP flap. In certain aspect, the present disclosure also provides an obturator component for maintaining the stoma or lumen.

Abstract: In accordance with some preferred embodiments, without limitation, the present invention comprises compositions, methods and systems for preparation of stem-cell enriched cell populations from sources of biological materials by sorting cell types in relation to size.

Abstract: The present invention is generally directed to a method for regulating cellular and tissue physiology, a device for practicing the method, and a process for fabricating the device. In general the process comprises the steps of providing at least one patterned electrode, providing a least one cell, placing the at least one electrode in electrical communication with the at least one cell, and applying a voltage to the electrode thereby delivering an effective amount of a patterned electric field or current thus regulating the physiology and/or growth of the at least one cell.

Abstract: Methods for the engineering and preparation of intervertebral disc repair scaffolds and articulating joint repair scaffolds are disclosed. The methodology utilizes either magnetic resonance images or combined magnetic resonance and computed tomography images as a template for creating either the intervertebral scaffold or the joint repair scaffold (e.g., osteochondral scaffold) with fixation to the underlying bone. The disc scaffold design may include an outer annulus that may contain desired structures and a central nucleus pulposus region that could either contain a designed microstructure or a contained hydrogel. The osteochondral scaffold may include a bone compartment interface with a cartilage compartment. The bone compartment may interface with a cutout portion of the bone through fixation components. Different microstructure designs may be created for the bone and cartilage compartment to represent desired mechanical and mass transport properties.

Abstract: The present invention discloses a composite made of a layer of epithelial cells cultured together with a dermal matrix in a culture medium, which is free of BPE. The dermal matrix is a substantially non-immunogenic human dermis. Also disclosed is an enhanced composite where a biological agent has been introduced into the epithelial cells. The invention also comprises methods of making and implanting both the composite and the enhanced composite in an animal. A method of treating disease or injury through the use of the disclosed composites is also part of the present invention.
