Area of Science:

  • Cell Biology
  • Developmental Biology
  • Biochemistry

Background:

  • Apoptosis is essential for tissue morphogenesis and adult homeostasis, regulating cell mass by eliminating aged cells.
  • Morphological signs of apoptosis are downstream effects of a complex biochemical cascade, intricately linked with cell differentiation.
  • Appreciating the specific links between differentiation and apoptosis requires analyzing the entire cascade, not just final morphological stages.

Purpose of the Study:

  • To review the main stages of the apoptosis cascade.
  • To outline current methods for morphological visualization of apoptosis.
  • To provide technical advice for studying differentiation and apoptosis, particularly in human placental trophoblast.

Main Methods:

  • Review of biochemical pathways involved in apoptosis.
