Gene Expression Profiles of Human Fetal Nasopharyngeal Tissue.
To study differentially expressed genes in nasopharynx tissues of embryo during development, and to observe the gene changes, total RNAs were respectively extracted from the nasopharynx tissue which came from fetuses of 5, 6, 7, and 8 month, Probes were yielded by reverse transcription and were used to hybridize with the Atlas(TM) human cDNA expression arrays. The results showed that the genes expression profile were distinctly different and different expression levels were found in the same gene during development. Results indicated that gene expression pattern had a character of time-dependence, such as early growth response protein 1 and the cDNA expression array provided a powerful method for studying gene expression profile in a large range of genes.
