Tetraploidy in hydatidiform moles.
STUDY QUESTION How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins? SUMMARY ANSWER Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote. The frequency of zygotic tetraploidy was estimated to be 0.7%. WHAT IS KNOWN ALREADY The parental orig...
متن کاملSex chromatin of hydatidiform moles.
The placenta is a homograft which is tolerated by the host for an unusually long time. The hydatidiform mole may be said to be even more successful in this respect for it can survive longer and penetrate further in the host even in the absence of a viable foetus. Recent observations that a large number of hydatidiform moles are chromatin positive are of much interest, but so far the reported se...
متن کاملQuantitative morphometrical characterization of human pronuclear zygotes.
BACKGROUND Identification of embryos with high implantation potential remains a challenge in in vitro fertilization (IVF). Subjective pronuclear (PN) zygote scoring systems have been developed for that purpose. The aim of this work was to provide a software tool that enables objective measuring of morphological characteristics of the human PN zygote. METHODS A computer program was created to ...
متن کاملThe maternally transcribed gene p57(KIP2) (CDNK1C) is abnormally expressed in both androgenetic and biparental complete hydatidiform moles.
Hydatidiform mole (HM) is an abnormal gestation characterized by trophoblast hyperplasia and overgrowth of placental villi. The genetic basis in the vast majority of cases is an excess of paternal to maternal genomes, suggesting that global misexpression of imprinted genes is the common molecular mechanism underlying the genesis of this condition. Although most complete HM are androgenetic in o...
متن کاملSTR DNA genotyping of hydatidiform moles in South China.
OBJECTIVE To evacuate whether short-tandem-repeat (STR) DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles. METHODS 150 cases were selected based on histologic features that were previously diagnosed or suspected molar pregnancy. All sections were stained with hematoxylin as a quality control method, and guided the microscopic dissection. DNA was extra...
