Provided is a gene therapy composition for transferring one of a therapeutic gene, a maker gene, or a mixture thereof to a cell that expresses interleukin-8 (IL-8) or GRO-&#x3b1; and induces tropism of mesenchymal stem cells isolated from umbilical cord blood and/or the mesenchymal stem cells expanded from said mesenchymal stem cells (UCB-MSCs), wherein the cell-treating composition includes UCB-MSCs. Provided is a composition for treating disease related to a cell expressing IL-8 or GRO-&#x3b1;, that is, a brain tumor in gene therapy, by using UCB-MSCs. Provided is a composition or kit for diagnosing brain tumors, preventing brain tumors, treating brain tumors, or monitoring brain tumor treatment progression by using UCB-MSCs.

UCB-MSCs comprising a tumor suppressor gene reduce the size of an IL-8 or GRO-&#x3b1;expressing tumor

A semiconductor memory cell comprising a capacitor for storing data thereon, and a first transistor being switched in response to a logic state of a word line. The first transistor writes data on a bit line into the capacitor, reads the data stored on the capacitor and transfers the read data to the bit line. The semiconductor memory cell further comprises a second transistor being switched in response to the logic state of the word line. The second transistor writes data on a bit line bar into the capacitor, reads the data stored on the capacitor and transfers the read data to the bit line bar. The semiconductor memory cell further comprises a transistor device for holding the data stored on the capacitor. According to the present invention, the semiconductor memory cell has a reduced number of devices as compared with a conventional one to enhance a chip integration degree. Also, the semiconductor memory cell prevents a current path from being formed therein to reduce its power consumption and compensates for a charge leakage to always hold its written data at a stabilized state with no loss.
