Hoe uitzaaiende tumoren hun omgeving naar hun hand zetten
Tumoren gedragen zich als mini-orgaantjes, manipuleren hun omgeving en gebruiken lichaamseigen processen om te overleven en uit te zaaien. Door onderzoek van Erik Danen en zijn collega’s komen we steeds meer te weten over de complexe aard van tumorcellen. In het NRC vertellen de wetenschappers over…
