Out, the fetus main stem cell in parent wrapping for using in lifetime gene analyzing differs the enlargement

摘要

(57) Abstract Manner of this invention makes lifetime when it does not have the fact that it invade tissues the space of the fetus making use of the blood of the pregnancy woman and the amplification of the fetus cell, diagnosis appear easy. As for this manner, invasive Characteristic is less than the amniotic fluid stab or chorion hair sampling and simple. Because, only the process which in order to obtain the fetus cell sample takes the blood from the parent includes. When there is a disease of the specification which is inspected and possesses known numerator mutation, the cell from this sample is the resource of DNA which enriched is done concerning the fetus material. When this disease is related to the erythrocyte, this manner offers the fetus erythrocyte cell for analysis. This disease can be used when it is related to the leucocyte, because various site Cain generate the fetus leucocyte choice. When the heterochromosome pattern which does not have the diagnostic danger (for example, advanced age of parent) of specification is inspected, this culture manner offers the process which splits the cell of the fetus beginning.
