  3. Embryology • Human development is a continuous process that begins when a zygote is formed • Development does not stop at birth

  4. Developmental Periods • Gametogenesis • Spermatogenesis • Oogenesis • Prenatal period (Fertilization) • Embryo: Zygote • Cleavage • Implantation • Gastrulation • Organogenesis • Fetus • Postnatal period • Neonate (<1 month) • Infancy (< 1 yr) • Childhood • Puberty (13 yr – 16 yr) • Adulthood

  5. LNMP (last normal menstrual period) 胎齡: fetus embryo Trimester

  6. 測量胚胎大小: 最大長 頂臀長 頂踵長

  7. Carnegie stagesare a system used by embryologists to describe the apparent maturity of embryos 1st trimester

  8. 1st week

  9. Formation of Bilaminar Embryonic Disc Stage 5: 7th –12th day full implantation 2nd week

  10. Stages 6-9: Day 13-21 Somites 3rd week

  11. Stages 10-17 4th to 6th week

  12. 7 8 • Embryo(end of the 8th week) - all major structures are present • Fetus(after 8th week)

  13. Genetics and Molecular biology are applied in human development • Ian Wilmut [1997] Somatic cell nuclear transfer – Dolly lamb • Embryonic stem cell

  14. Somatic cell nuclear transfer

  15. Stem cell Embryonic stem cell Morula Blastocyt
