We describe the use of an exosome for the preparation of a pharmaceutical composition to promote or enhance would healing or hair growth, or both, in an individual. The exosome may be derived from a stem cell such as a mesenchymal stem cell (MSC).

The present disclosure relates to compositions capable of absorbing UVA and UVB light. In particle, the present disclosure relates to UV screening compositions comprising at least a portion of LITE-1 polypeptides which are capable of absorbing UV light (e.g., UV-A and/or UV-B light).

The present invention relates to the fields of medicine, cell biology, molecular biology and genetics. In particular, the present invention provides methods to isolate and purify microvesicles from cell culture supernatants and biological fluids. The present invention also provides pharmaceutical compositions of microvesicles to promote or enhance wound healing, stimulate tis -sue regeneration, remodel scarred tissue, modulate immune reactions, alter neoplastic cell growth and/or mobility, or alter normal cell growth and/or mobility. The present invention also provides compositions of microvesicles to be used as diagnostic reagents, and methods to prepare the compositions of microvesicles.

Apparatus and methods for separating blood components are disclosed in which an apparatus for separating blood generally includes a tube defining a channel and configured for receiving a quantity of blood and a float contained within the tube and having a density which is predefined so that the float is maintained at equilibrium between a first layer formed from a first fractional component of the blood and a second layer formed from a second fractional component of the blood. Upon completion of the centrifugation, the first layer may be removed from the tube while the float isolates the second layer from the first layer.

The purpose of the present invention is to provide an oil/lipid that contains dihomo-γ-linolenic acid at a higher purity. Provided is a microbial oil/lipid that is specified by a high content of dihomo-γ-linolenic acid contained therein and/or a reduced content of undesirable constituting fatty acid(s).

The present invention relates to a composition with an antioxidant activity, comprising a first dry extract derived from plant cell cultures comprising superoxide dismutase of Sulfolobus solfataricus, a second dry extract derived from plant cell cultures comprising superoxide dismutase of Aeropyrum pernix and a third dry extract derived from plant cell cultures comprising superoxide dismutase from Deinococcus radiodurans, wherein said plant cell cultures are cultures of cells belonging to Solanum lycopersicum species.
