Abstract: Longarm mullets Moolgarda cunnesius (Valenciennes, 1836) belong to the family Mugilidae. They are found in fresh, brackish and salt water and distribute in Indo-West Pacific. In this study, mitochondrial cytochrome oxidase subunit I gene (COI) were employed to investigate the genetic diversity of longarm mullets. M. cunnesius individuals were collected from Tam Giang lagoon (n=10) and Thua Thien Hue sea coast (n=9) were examined. Nineteen COI gene fragment sequences were deposited in GenBank database with accession numbers MW336937-MW336955. Among 19 sequences of COI gene fragment, 11 distinct haplotypes were defined. Although the population haplotype diversity (Hd) was generally high (0.833 and 0.756), the nucleotide diversity (π) was relatively low (0.00276 and 0.00265) among the two populations. Additionally, the genetic distances ranged from 0-0.99% within the populations and the genetic distance between the two populations was 0.27%. Our study showed the population genetic diversity and structure of longarm mullets M. cunnesius in Thua Thien Hue, Vietnam.

Abstract: Stem cells are derived from embryonic and non-embryonic tissues. Most stem cell studies are for animal stem cells and plants have also stem cell. Stem cells were discovered in 1981 from early mouse embryos. Stem cells have the potential to develop into all different cell types in the living body. Stem cell is a body repair system. When a stem cell divides it can be still a stem cell or become adult cell, such as a brain cell. Stem cells are unspecialized cells and can renew themselves by cell division, and stem cells can also differentiate to adult cells with special functions. Stem cells replace the old cells and repair the damaged tissues. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. This article introduces recent research reports as references in the related studies.
