Isolation of human dermis derived mesenchymal stem cells using explants culture method: expansion and phenotypical characterization.

Recent studies have reported that stem cells can be isolated from a wide range of tissues including bone marrow, fatty tissue, adipose tissue and placenta. Moreover, several studies also suggest that skin dermis could serve as a source of stem cells, but are of unclear phenotype. Therefore, we isolated and investigated to determine the potential of stem cell within human skin dermis.

Nicotine inhibits the proliferation by upregulation of nitric oxide and increased HDAC1 in mouse neural stem cells.

Cigarette smoking (CS) is considered one of the major risk factors to cause neurodegenerative disorders. Nicotine is the main chemical in CS which is responsible for dysfunction of the brain as a neuroteratogen. Also, nicotine dependency is a real mental illness and disease.

Generation and analysis of end sequence database for T-DNA tagging lines in rice.

We analyzed 6749 lines tagged by the gene trap vector pGA2707. This resulted in the isolation of 3793 genomic sequences flanking the T-DNA. Among the insertions, 1846 T-DNAs were integrated into genic regions, and 1864 were located in intergenic regions.
