  • Work started during the pandemic and shortages.
  • The lab could not get an important gel.
  • The student and adviser decided to make one.
  • They used a gel made from tiny algae.
  • The gel supports mammary cells that form ducts.
  • Scientists can change gel stiffness and chemistry.
  • This lets them direct how cells grow.
  • Good cues make cells develop normally in gel.
  • Wrong cues cause cells to make other proteins.
  • Researchers hope to grow complex tissues from patients.
