Abrégé

Compositions of culture conditions and the stepwise method for improving reprograming of human somatic cells into human chemically induced pluripotent cells are disclosed. The first stage, which uses a combination of small molecules with necessary biological activities, is aimed at downregulating the somatic gene program. The second stage uses a selection of small molecules with select biological activities to upregulate one or more pluripotency-related transcriptional factors. The third stage uses a selection of small molecule factors with select biological activities to establish an initial pluripotency network, measured by the expression of OCT4. The fourth and final stage uses a selection of small molecules with select biological activities to fully establish a pluripotent network, measured by co-expression factors such as OCT4, SOX2, and NANOG in the reprogrammed cells. The resultant reprogrammed cells are termed human chemically induced pluripotent stem cells, hCiPSCs.

Disclosed is a use of a SUSD2 protein as a marker, in particular a use of the SUSD2 protein as the marker in identification, selection or separation of pancreatic internal secretion precursor cells and/or newborn pancreatic internal secretion cells; and a use of an mRNA, for encoding the SUSD2 protein, of a precursor protein as the marker in identification of the pancreatic internal secretion precursor cells and/or the newborn pancreatic internal secretion cells.Through analysis of gene expression of pancreatic endoderm cells sourced by induced directional differentiation of human pluripotent stem cells, the enrichment expression of a SUSD2 gene in the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells is found. In addition, a protein encoded by the SUSD2 gene is a receptor protein on cell membranes. Using the protein as the marker, the identification, the selection or the separation of the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells can be carried out, which has an important significance on research about pancreas related cells in each development stage.

A method for inducing reprograming of a cell of a first type which is not a non-hepatocyte (non-hepatocyte cell), into a cell with functional hepatic drug metabolizing and transporting capabilities, is disclosed. The non-hepatocyte is induced to express or overexpress hepatic fate conversion and maturation factors, cultured in somatic cell culture medium, hepatocyte cell culture medium and hepatocyte maturation medium for a sufficient period of time to convert the non-hepatocyte cell into a cell with hepatocyte-like properties. The iHeps induced according to the methods disclosed herein are functional induced hepatocytes (iHeps) in that they express I and II drug-metabolizing enzymes and phase III drug transporters and show superior drug metabolizing activity compared to iHeps obtained by prior art methods. The iHeps thus provide a cell resource for pharmaceutical applications.

Abrégé

A method for removing SO x from a gas by using a modified polyethylene glycol solution to absorb the SO x in the gas. The modified polyethylene glycol solution is contacted with the gas containing SO x to absorb the SO x in the gas, wherein x = 2 and/or 3, the modified polyethylene glycol is a product derived from etherifying hydroxyl groups in the molecules of ethylene glycol and/or polyethylene glycol and has a general formula: R1-(O-C2H4)n-O-R2, where n is a positive integer, R1 and R2 are the same or different and are each independently alkyl, alkenyl, alkynyl, acyl or aryl.

Abrégé

A method for removing SO x (x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SO x in the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SO x is regenerated by one or more of the heating, vacuum, ultrasonic, microwave or radiation methods, thereby releasing the by-products of sulfur dioxide and sulfur trioxide. The regenerated solution of polyethylene glycol is recycled. When the water content of the regenerated solution of polyethylene glycol is high enough to affect the desulfurization, it needs to be removed. Removal methods include heating and rectification, absorption using a water absorbent, or a combination of these methods. The polyethylene glycol solution is recycled after dehydration.
