实验参考方法

Cell experiment [1]:

Cell lines

Human and rat neural progenitor cells (NPCs)

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

0, 1, 2, 5 and 10 μM; 24 or 48 hrs

Applications

(-)-Epigallocatechin Gallate (EGCG) altered human and rat NPC development in vitro. EGCG affected migration distance, migration pattern and nuclear density of NPCs growing as neurospheres. EGCG exerted these functional impairments by binding to the extracellular matrix (ECM) glycoprotein laminin, preventing its binding to β1-integrin subunits, thereby prohibiting cell adhesion and resulting in altered glia alignment and decreased number of migrating young neurons.

Animal experiment [2]:

Animal models

A rat model of partial bladder outlet obstruction (pBOO)-induced bladder injury

Dosage form

4.5 mg/kg/day; i.p.; 2 days or 30 days

Applications

EGCG attenuated bladder inflammation caused by pBOO at the 48th hr. At the 30th day, EGCG attenuated endoplasmic reticulum (ER) stress-related apoptosis. In addition, EGCG improved bladder compliance, contractile frequency and inflammation at the 30th day.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
