Insights

Preeclampsia affects endothelial progenitor cells (EPCs), impacting infant cardiovascular health. This study shows these cells can be rejuvenated, offering hope for improved infant outcomes.

Area of Science:

  • Cardiovascular Biology
  • Maternal-Fetal Medicine
  • Cellular Biology

Background:

  • Preeclampsia is a major cause of maternal and infant mortality.
  • Infants born from preeclamptic pregnancies face increased risks of cardiovascular disease.
  • Endothelial progenitor cells (EPCs), specifically endothelial colony-forming cells (ECFCs), are implicated in these complications due to stress-induced dysfunction.

Approach:

  • Cord blood-derived ECFCs from preeclamptic pregnancies (PRECs) were isolated and compared to healthy ECFCs.
  • Phenotypic and functional characteristics of PRECs were analyzed, focusing on endothelial markers, oxidative stress, and inflammatory responses.
  • The effect of neuropilin-1 treatment on ECFC function was investigated *in vitro*.

Key Points:

  • PRECs maintain endothelial markers but show increased oxidative stress and inflammatory markers.
  • PRECs exhibit reduced migratory capacity and impaired angiogenic potential compared to healthy ECFCs.
  • Neuropilin-1 treatment demonstrated potential to improve tube formation in PRECs *in vitro*.

Conclusions:

  • The preeclamptic environment alters the phenotype and function of ECFCs.
  • Exogenous molecules, like neuropilin-1, can rejuvenate dysfunctional PRECs.
  • Rejuvenated PRECs hold promise for improving lung function in infants born from preeclamptic pregnancies.

Zygotic Development And Stem Cell Formation01:10

Zygotic Development And Stem Cell Formation

The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
Embryonic Connective Tissues01:20

Embryonic Connective Tissues

During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Development of Blood Vessels01:07

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
