Human brown adipose derived stem cells and uses
An isolated human brown adipose tissue stem cell line. In one embodiment, the isolated human brown adipose tissue stem cell line expresses the markers CD9, SSEA4, CD44, CD90, CD166, CD73, but not CD14, CD34, CD45 or STRO-1. In another embodiment, the isolated human brown adipose tissue stem cell line expresses the genes UCP1, PPARGC1A, NRF1, FOXC2, CREB1, SIRT3, and WNT5A (REFX). In still another embodiment, the isolated human brown adipose tissue stem cell line is capable of differentiating into osteoblasts, chondrocytes, and adipocytes.
1. An implantable construct comprising:
a scaffold; and
an isolated human neonatal brown adipose tissue stem cell cultured on the scaffold;
wherein the isolated human neonatal brown adipose tissue stem cell is cultured in a culture medium comprising fibronectin type III domain-containing protein 5 (FNDC5) and differentiates into a human neonatal brown adipose tissue differentiated cell;
wherein UCP-1, ELOVL3, and PGC1A gene expression is upregulated in the human neonatal brown adipose tissue differentiated cell.
2. The implantable construct of claim 1 , wherein the scaffold comprises a porous extracellular matrix.
3. The implantable construct of claim 1 , wherein the isolated human neonatal brown adipose tissue stem cell is derived from a one day old male neonate.
