  • Antibody development against proteins and synthetic peptides for localization studies.
  • In situ hybridization for mRNA determination and cell culture for studying matrix synthesis and regulation.
  • cDNA library construction for gene isolation and characterization.

Main Results:

  • Identification and purification of major structural and growth factor proteins in mineralized tissues.
  • Availability of antibodies and mRNA data for precise localization of matrix constituents in bone.
  • Development of cell culture models for studying matrix regulation.
  • Isolation and characterization of genes encoding matrix proteins.

Conclusions:

  • Current techniques enable comprehensive assessment of matrix protein roles in mineralized tissues.
  • This understanding is critical for deciphering bone metabolism in both health and disease states.
