Pnipam cell sheet engineering

While it is known that the NIPAM monomer is toxic, there is little conclusive research on the cytotoxicity of the polymer. field of cell- sheet engineering [ 10– 13]. Various types of N- isopropylacrylamide ( NIPAM) containing copolymers have been used as “ intelligent layers” to control cell- surface pnipam adhesion,,,,. PNIPAM microgels were also deposited pnipam in micropatterns on substrates for the cell sheet engineering application. 12 国家自然科学基金项目“ 考虑化学反应的固体多场耦合力学问题研究”.

A promising tissue engineering approach relies on the use of cell culture surfaces grafted with poly( N- isopropylacrylamide) ( PNIPAM, Prod.

Cell sheet harvest technology enables fabrication of viable, transplantable cell sheets for various tissue engineering applications. However non- functionalized PNIPAM cannot be well applied for cell cultivation due to the low cell adhesion. pnipam Poly( N- isopropylacrylamide) ( variously abbreviated PNIPA PNIPAA , PNIPAAm, NIPA PNIPAm) is a temperature- responsive polymer that was first synthesized in the 1950s. Thermosensitive poly( N- isopropylacrylamide) ( PNIPAM) - based substrates have presented great promise in cell sheet engineering. Poly( N- pnipam isopropyl pnipam acrylamide) ( pNIPAM) is one of the most popular stimulus- responsive polymers for research. It can be pnipam synthesized from N- isopropylacrylamide which is commercially available. A simple dip coating method was employed to micropattern flat substrates with PNIPAM particles in a template free manner. 2 The basic idea is that cell adhesion/ detachment on PNIPAM- modified substrates can be achieved by a simple temperature switch ( Figure 1). 12 国家自然科学基金重大项目课题“ 层状.

Especially pnipam for applications such as engineering cell sheets engineering drugs is varied to the thickness , drug delivery, the pnipam efficiency of attachment/ detachment of certain cell types density of pnipam grafted pnipam pNIPAm. Smart Biomaterials for Cell Sheet Engineering by Deirdre Healy, B. Cell sheet engineering has been progressing rapidly during the past few years and has emerged as a novel approach for cell based therapy. The Cell Sheet Tissue Engineering Center at the University of Utah was established in by Dr. It is especially of great interest in the field of tissue engineering. With decreasing temperature below the pnipam LCST the hydrogel surface becomes hydrophilic , the cell sheet detaches spontaneously from the surface without enzyme digestion which may damage the cell membrane [ 8]. Cell sheet engineering is based on the control of cell adhesion so that intact sheets of confluent cells may be recovered with minimal damage to cell structure function. 12 国家自然科学基金项目“ 自修复材料的宏观模拟与细观分析”.

Although there is a great deal of research focused on cell sheet engineering from polymers such as poly( N - isopropyl acrylamide) ( pNIPAM) the biocompatibility of pNIPAM surfaces the nature of cellular detachment from this polymer is still unclear. pnipam pnipam 5 深圳市基础研究( 自由探索) 项目“ 固体热- 化- 力多场耦合问题的建模与分析”.
