Molecular diagnosis of sex chromosome mosaics in fetal amniotic cells

Molecular diagnosis of sex chromosome aneuploidy using quantitative PCR.

Numeric sex chromosome imbalances, or aneuploidies, are present in several pathological conditions including tumors, abnormal gestations, and clinical syndromes. Here we report a method to identify karyotypic imbalances of the X and Y chromosomes using the polymerase chain reaction (PCR). The polymerase chain reaction was used to quantitatively coamplify the sex chromosome linked genes ZFX and ...

Karyotype and Sex-Chromosome Polymorphism in Nesokia indica, from Iran

Amniotic mesenchymal stem cells enhance normal fetal wound healing.

Fetal wound healing involves minimal inflammation and limited scarring. Its mechanisms, which remain to be fully elucidated, hold valuable clues for wound healing modulation and the development of regenerative strategies. We sought to determine whether fetal wound healing includes a hitherto unrecognized cellular component. Two sets of fetal lambs underwent consecutive experiments at midgestati...

Molecular Analysis of Sex Chromosome Evolution in Papaya By

Papaya is a semi-woody tree that produces fruit rich in vitamins and minerals. It is trioecious with male, female, and hermaphrodite plants. Though many theories have been suggested in the past, papaya sex is determined by a pair of nascent sex chromosomes; females have two X chromosomes, males have an X and a Y, and hermaphrodites have an X and a Y, which varies slightly from the male Y. Any c...
