Abstract:
본명세서에는진피유래성체줄기세포의신규한용도와줄기세포의혈관생성능력을탐지하는방법이개시된다. 상기인간진피유래성체줄기세포(human dermal stem/progenitor cells, 이하 hDSPCs)를유효성분으로함유하는조성물은, 혈관생성능력을보유하고있는바피부에건강한혈관을공급해줌으로써피부노화의개선또는억제, 피부상처치유또는피부혈행개선의효과를가질수 있다. 또한, 배양접시내에형성된신생혈관을대조군과비교하여줄기세포의혈관생성능력을탐지할수 있다.
Abstract:
PURPOSE: A composition containing miRNA for controlling pigmentation gene expression is provided to suppress tyrosinase, tyrosinase-related proteins, and melan-A expression. CONSTITUTION: A composition for controlling pigmentation gene expression contains miRNA containing a base of sequence number 1 as an active ingredient. The miRNA has continuous 27 bases containing ccuucuu of sequence number 1 and a base which suppresses pigmentation gene expression. The pigmentation gene is tyrosinase, tyrosinase-related protein 1, or melan-A gene. The miRNA targets 909-915th nucleic acids of melan A mRNA 3'-UTR. The composition is a cosmetic or pharmaceutical composition for skin whitening. A composition for controlling pigmentation gene expression contains a complementary base with miRNA of sequence number 1.

Abstract:
PURPOSE: A composition containing an oligonucleotide or mimic acting as an inhibitor of miRNA-526b is provided to control collagen generation and to prevent or treat aging. CONSTITUTION: A composition for controlling collagen contains 15-23 serial nucleotides of sequence number 1. The collagen is controlled by regulating the expression of matrix metalloproteinase 1(MMP1). The oligonucleotide reduces or suppresses the expression of MMP1 by hybridization with MMP1 mRNA. The composition is used for anti-aging.
