Summary

Objectives

  • Understanding how individual cells are made up of tissues and organs.

  • Being able to observe different properties of tissues,
  • Being able to explain how tissue differentiation originates.

Summary

  • All human cells are derived from a cell created by the fusion of an egg and a sperm nucleus in fertilisation.
  • Cells formed in the initial stage of a fertilised egg are totipotent stem cells.
  • The cells differentiate from similar stem cells into different tissues and organs.
  • Tissue cells are similar.
  • Stem cell differentiation is a complex process driven by genes.
  • Nowadays, stem cells can be cultured and developed into the desired cells.
  • Keywords: cell, tissue, organ, body, stem cell, differentiation, nerve tissue, muscle tissue, connective tissue, epithelial or surface tissue.
