摘要:
Disclosed is a method for removing polynucleotide from the skin. This polynucleotide can be used to detect dermatitis and distinguish an irritant reaction from an allergic reaction by charaterizing the polynucleotide according to the polypeptide which it encodes. Additionally, provided are methods for non-invasive isolation of samples from the skin as well as kits for use in the methods provided herein.
摘要:
This invention provides a substantially pure population of educated, antigen-specific immune effector cells expanded in culture at the expense of hybrid cells, wherein the hybrid cells are antigen presenting cells (APCs) fused to cells that express one or more antigens and methods of using the population of cells.
摘要:
Methods for producing thin keratin films, sheets, and bulk materials, and products formed using these methods. The keratin film may be used as a wound dressing, a tissue-engineering scaffold, a diffusion membrane, a coating for implantable devices, and as a cell encapsulant. The keratin bulk product can be used as a cross-linked implantable biomaterial for soft and hard tissue replacement.
摘要:
Disclosed herein are designer extracellular vesicles (EVs) that target Schwann cells (SCs). For example, in some embodiments, the EVs are decorated with HRG1/2, NRG1, or a combination thereof. These EVs can in some embodiments, be used to deliver diagnostic and/or therapeutic cargo to Schwann cells in a subject in need thereof.
摘要:
Provided are engineered cells containing one or more modifications, such as genetic modifications, for use in allogeneic cell therapy. In some embodiments, the engineered cells are hyopimmunogenic cells. In some embodiments, the engineered cells comprise reduced expression of CD 142 and/or are administered in combination with an anti-coagulant.
摘要:
Compositions and methods involving microspheres composed of mesenchymal cells such as dermal papilla cells (DPCs) and extracellular matrix, epithelial cell such as keratinocyte are disclosed. It has been discovered that by balancing the proportion of DPCs and extracellular matrix in the DPC-matrix mixture, and by incubating a particular range of small volume of the DPC-matrix mixture, DPC-matrix microspheres can be formed that have useful properties. Most significantly, the resulting DPC-matrix microspheres are particularly suited to be used to produce bioengineered hair follicles that have features of native hair follicles.
摘要:
Provided herein is method of treating a skin condition in a subject, comprising isolating cells comprising primary dermal fibroblasts from a skin sample obtained from the subject, and administering the freshly-isolated cells to skin of the subject. Also provided are freshly isolated cell preparations comprising primary dermal fibroblasts and uses thereof.
