Fetal Cell Receptors Repertoire

"Study of CCR Receptor Overexpression in Fetal Microchimeric Cells: Proof of Concept Before a Potential Clinical Trial"


Sponsor

Assistance Publique - Hôpitaux de Paris

Enrollment

160 participants

Start Date

Feb 6, 2024

Study Type

INTERVENTIONAL

Conditions

Summary

The purpose of this study is to describe the transcriptomic profile of foetal cells in post-partum and more specifically to determine which chemokine receptors are overexpressed in foetal cells in post-partum women with wounds To do so, the investigators will isolate foetal cells from the peripheral blood of healthy controls post partum women as well as from post partum women with skin ulcers and then perform RNA sequencing.

Interventions

OTHERSaliva sampling

HLA genotyping. The technique should allow to identify, for children's, a paternal HLA antigen not shared with the mothers.

OTHERBlood sampling

Maternal Blood samples will be incubated with the appropriate antibody, targeting the microchimeric fetal cells of each patient, as well as with a cell viability marker (DAPI). The samples were then be processed through the BD FACS Aria III to sort the fetal cells, The following steps - RNA extraction, quality control, retrotranscription, preparation of the library, sequencing and transcriptomic analysis - will be carried out according to the Smart-seq3 protocol. The data will be sent for in-depth analysis and confirmation of the results. Additional functional experiments may also be carried out.
