Cells in maternal blood, which involve male chromosome or paternal gene, are fetal origin.
The collected cells having Y chromosome are fetal cells. |

Paper was submitted to an international journal. |
The collected cells having paternal DNA are fetal cells. |
|
Paternal DNA was directly extracted and detected from the adherent cells after SLM.

Collaborative research with other BioTech |
The above-mentioned researches show that the cellular fraction after SLM enrichment certainly involves the cells of fetal origin.
SLM supplies sufficient erythroblasts to analyze aneuploidy using FISH.
- Image analyzer: Metafer4/AXIO (Carl Zeiss, Jermany)
- FISH probes: GSP Lab. (Kanagawa Japan)
- Venous blood of pregnant women after post diagnosis were collected, and then IIIIconducted SLM.
- Hemolysis after blood drawing occurred on the individual 4. Hemolysis may
- BIBhave reduced the number of erythroblast detection.
SLM is a practical technique to supply fetal whole genomes as erythroblast.
