Urmărește-ne pe DiscoverUn nivel ridicat al stresului afectează celulele suşă care dau culoarea firelor de păr, provocând albirea lor. Cercetătorii de la Universitatea Kanazawa din Japonia au studiat efectele stresului asupra firelor de păr din blana şoarecilor.
Blana şoarecilor expuşi unor teste de inducere a stresului s-a albit mai devreme, pe măsură ce celulele prezente în foliculii firelor de păr au fost obligate să se maturizeze, reducând producţia de melanină, substanţa responsabilă pentru culoarea părului şi a pielii.
David Fisher, şeful Departamentului de dermatologie de la Harvard Medical School, a declarat că, prin blocarea diviziunii celulelor suşă a căror structură ADN a fost afectată, se poate preveni apariţia tumorilor canceroase.
