The present invention provides a composition for preventing, ameliorating, alleviating or treating dermatitis comprising exosomes derived from adipose-derived stem cells as an active ingredient. The composition of the present invention is able to act against dermatitis-inducing multiple cytokine targets, and thus be widely applied against dermatitis caused by various factors and effectively suppress and alleviate dermatitis.

Disclosed herein are methods and compositions for modulation of telomere length in cells. Aspects are directed to reduction in telomere shortening rate, stabilization of telomere shortening, and/or telomere elongation using fibroblasts or fibroblast-derived products. In some cases, provided are methods for treatment of telomere-associated conditions using fibroblasts or fibroblast-derived products. Fibroblasts may be provided to modulate telomere length in cells of a subject, thereby treating a telomere-associated condition such as, for example, cancer, aging, or idiopathic pulmonary fibrosis.

A composition inhibiting MEIS proteins. The MEIS proteins are effective in proliferation of hematopoietic stem cells. A formulation capable of easily passing through the cell membrane and perform its activity in the cell, and can inhibit MEIS activity in a dose dependent manner. The combination includes isolated cells, medium, growth factors and MEISi inhibitor. The isolated cells are isolated from mouse bone marrow, human bone marrow and human umbilical cord blood. The medium has a pH value of 7.2 and contains bovine serum albumin, recombinant insulin, transferrin, 2-mercaptoethanol and IMDM medium. The growth factors are hematopoietic stem cell factor SCF, fetus liver tyrosine kinase-3 ligand Flt3L, and thrombopoietin. A chemical formula of the MEISi-1 is 4-[2-(benzylamino)-2-oxoethoxy]-N-(2,3-dimethylphenyl) benzamide. A chemical formula of MEISi-2 is 4-hydroxy-N′-[(Z)-(2-oxonaphthalen-1-ylidene)methyl] benzohydrazide.
