Abstract:
The present invention relates to improved continuous (immortalized) cell lines, in particular keratinocytes and melanocytes derived from normal human skin tissue. The present invention also relates to novel serum-free media for isolating, producing and maintaining said improved continuous keratinocyte and melanocyte cell lines. The present invention also relates to methods for producing primary melanocytes and keratinocytes under serum-free conditions without any feeder cells.
Abstract:
Provided are methods, apparatus, pharmaceutical compositions, and kits for treatment of a metabolic condition, including obesity and type 2 diabetes, by administration to a subject of a therapeutically effective amount of a cell or tissue preparation such as brown adipose microtissues or brown adipose tissue directly converted from white adipose tissue. Modified approaches to creating brown adipose tissue involve differentiation of explanted white adipose tissue and direct browning of white adipose tissue in a bioreactor rather than isolation and expansion of adipose stems cells or endothelial cells and formation and differentiation of 3D cell aggregates.
Abstract:
The present invention relates to organoids derived from a single cell, such as a prostate cancer cell, and methods and compositions relating to the production and use thereof, including cell culture medium for producing organoids and methods of personalized treatment for prostate cancer. The invention further provides a humanized mouse comprising a prostate organoid derived from a patient's prostate cell.
Abstract:
L'invention a pour objet une population d'adipocytes bruns humains fonctionnelle, dans laquelle l'expression de UCP1, CIDEA, CPT1B et Bc12 est supérieure, l'expression de Bax est inférieure, et l'expression de PPAR alpha, PGC1 alpha, PGC1 bêta et PRDM16 est similaire par rapport aux expressions correspondantes d'une population d'adipocytes blancs humains. L'invention concerne également un procédé de différenciation de cellules hMADS en la population d'adipocytes bruns humains fonctionnelle, un procédé de conversion d'une population d'adipocytes blancs humains en la population d'adipocytes bruns humains fonctionnelle, ainsi qu'une méthode de criblage de molécules susceptibles de moduler le poids corporel chez un sujet.
Abstract:
Disclosed is a method for in vitro growing of connective tissue substitute, said connective tissue substitute being populated with fibroblasts, a connective tissue substitute obtainable by such a method, as well as a method for closing of a wound, wherein such connective tissue substitute is applied onto a wound.
Abstract:
The use of a simarouba extract (A) to produce (a) cosmetic or pharmaceutical (esp. dermatological) compsns. and (b) culture media for cells and tissues (partic. bulk culture of skin cells, esp. keratinocytes), is new. (A) have (1) depigmenting action and stimulate differentiation of keratinocytes and (2) restore, preserve, and/or reinforce the protective function of the skin (partic. its water-barrier function) cohesion of epidermal cells, and also improve quality of the hair.
Abstract:
A simarouba extract is used to produce a cosmetic or pharmaceutical, and particularly dermatological, composition or a skin cell culture medium. The resulting compositions are also disclosed. The simarouba extract has a significant skin depigmentation activity and can enhance the protective function of the skin, particularly its water barrier function, as well as having a significant keratinocyte differentiation activity.
Abstract:
The present invention relates to a method for generating melanocytes from stem cells comprising the steps of: (i) removing the bulb of an epilated human hair; (ii) incubating the remaining part of the epilated hair with a collagen degrading agent to separate stem cells from the outer root sheath; (iii) cultivating the separated stem cells from step (ii) in a medium that induces differentiation and stimulates growth of stem cells, melanocyte precursors and melanocytes, wherein the medium comprises one or more growth factors for differentiation into melanotic melanocytes. Furthermore, a method for producing an autograft, a homograft or an allograft comprising melanocytes is disclosed herein as well as autografts, a homografts and allografts or melanocytes for the treatment of diseases related to depigmentation of the skin or for the treatment of scars.
Abstract:
The invention provides a method of producing oligodendrocytes by in vitro differentiation of human multi-potent progenitor cells (MLPCs). The method comprises culturing culturing isolated MLPCs on a first surface in a serum-free defined culture medium; replacing the culture medium with serum-free culture medium supplemented with bFGF, EGF and PDGF-AA for approximately 24 hours; changing the cultured MLPCs into the supplemented serum-free culture medium further supplemented with differentiation factors norepinephrine, forskolin. and K252a; establishing a 3D environment by covering the culture with a second surface opposite and spaced apart from the first surface, so as to contain the MLPCs therebetween; and continuing to culture until a majority of the MLPCs have differentiated into oligodendrocytes. Additionally included is a method of treatment for a subject afflicted by a disease characterized by central or peripheral nervous system demyelination, the method comprising transplanting into the subject oligodendrocytes produced according to the method disclosed.
