Abstract:
Disclosed herein is a processing method of a microelectrode array. A processing method of a microelectrode array includes: depositing a sacrificial layer on a silicon substrate; patterning a first polymer on the deposited sacrificial layer and then thermally curing the first polymer patterning a metal thin film on the first polymer to form a bonding pad site, an interconnection line and a recording pad site; closing the interconnection line site and coating a second polymer to pattern the bonding pad site and the recording pad site; depositing a seed layer on the second polymer and the metal thin film using a sputter; electroplating a metal on the bonding pad site and the recording pad site, thereby forming an electroplated layer; patterning a photoresist to open an upper portion of the electroplated layer; depositing platinum on the photoresist and the electroplated layer; and removing the photoresist.
Abstract:
The present invention relates to a method for differentiating stem cells into vascular cells by culturing them in the form of a three-dimensional cell cluster and the use of the three-dimensional cell cluster for angiogenesis. Specifically, the present invention teaches a method for differentiating stem cells into vascular cells comprising culturing stem cells by adhering them onto a culture plate with a surface having a hydrophobic property or a culture plate onto which a growth factor is immobilized, wherein the cultured stem cells are later detached from the culture plate as their density increases to form a three-dimensional cell cluster and grown in the form of a three-dimensional cell cluster while differentiating into vascular cells. Also disclosed is the use of a three-dimensional cell cluster composed of the vascular cells differentiated from stem cells by the above method as a cell therapy agent for angiogenesis.
