Alle procedures waarbij dierlijke onderwerpen zijn goedgekeurd door de institutionele Animal Care en gebruik Comité (IACUC) aan Weill Cornell Medical College. Alle xenotransplantatie experimenten met behulp van eierstokweefsel werden uitgevoerd volgens de relevante richtlijnen en verordeningen. Menselijke eierstokweefsel werd bijeengezocht uit patiënten gepland voor chemotherapie of radiotherapie voor behandeling van kanker of voorafgaande beenmergtransplantatie.

Hier tonen we dat mede transplantatie van exECs biedt een aanzienlijk voordeel eierstokweefsel levensvatbaarheid en functie na xenograft in muizen. Normen voor klinische toepassing van eierstokweefsel auto-transplantatie voor behoud van de vruchtbaarheid geweest niet set en de optimale parameters (grootte, transplantatie site, duur van de graft, enz.) 32 , 33 , 34 voor verbeterde herstel van het folliculaire zwembad bli...

Kanker blijft een van de belangrijkste doodsoorzaken in de ontwikkelde wereld, maar tientallen jaren onderzoek hebben aanzienlijke vooruitgang voor de meeste soorten van kanker, en in sommige gevallen bijna verdubbelde survival tarieven1opgeleverd. Helaas, chemotherapeutische agenten zijn vaak gonadotoxic, uitputting van de reserve van primordiale follikels in de eierstokken en een vermindering van de vruchtbaarheid2. Deze groeiende bevolking kan profiteren van de verschillende methoden voor het behoud van de vruchtbaarheid met inbegrip van de oöcyt en/of embryo cryopreservatie, patiënten vereisen snelle opening van kankertherapie en vooraf pubertijd patiënten zijn echter niet in aanmerking voor deze opties. Als alternatief, hebben sommige patiënten gekozen voor het cryopreserve van eierstokweefsel alvorens hun therapeutische regime, en bij herstel en vergeving, auto-verplanten weefsel herstellen vruchtbaarheid3. Echter tot op heden, blijven graft overleving en folliculaire uitvoer na auto-transplantatie relatief lage4, voornamelijk als gevolg van weefsel ischemie en hypoxie5,6,7. Ondanks de vele inspanningen ter verbetering van de levensvatbaarheid van ovariële corticale transplantaties met behulp van anti-oxidanten8,9, pro-angiogenic cytokines10,11,12,1 3, of mechanische manipulaties14, graft ischemie in een dag van 5 tot en met 7 venster na transplantatie ondermijnt de levensvatbaarheid en de overleving van de graft-7. Om aan te pakken dit, ontwikkelden we een cel-gebaseerde strategie om te vergemakkelijken wapendrager van host- en graft vaartuigen en dus haast reperfusie van eierstokweefsel.
Naast de ischemische belediging voor geënte ovariaal weefsel in het venster na transplantatie, kan de verstoring van Inter folliculaire signalering bijdragen aan de uitputting van de zwembad15,16. Omdat exogene endotheliale cellen (ExECs) tot een stabiele en goed functionerende vaartuigen in de periferie van de prothese bijdragen, presenteren ze een unieke kans om het overbrengen van een gedefinieerde moleculaire input aan getransplanteerde weefsel. Als een bewijs van beginsel, werden ExECs ontworpen om uitdrukkelijke Super fysiologische niveaus van Anti-Mullerian hormoon (AMH), een lid van de transformerende groeifactor bèta (TGFβ) superfamilie dat is aangetoond dat het beperken van de folliculaire groei17. Vergelijking van de folliculaire distributie in transplantaten samen met controle en AMH-uiten cellen getransplanteerd controleert de biologische activiteit en de potentie van gemanipuleerde exECs.
Kortom, door verbetering van de graft levensvatbaarheid en onderdrukken van vroegtijdige mobilisatie van de folliculaire pool, deze aanpak kan de productiviteit te verhogen van auto-getransplanteerde eierstokweefsel in patiënten die een behoud van de vruchtbaarheid. Bovendien kan de ExEC-gebaseerd platform experimentele ondervraging van moleculaire regelgevende instanties die zijn betrokken bij de ontwikkeling van de folliculaire.

co-transplantation of human ovarian tissue with engineered endothelial cells: a cell-based strategy combining accelerated perfusion with direct paracrine delivery

Onvruchtbaarheid is een frequente bijwerking van chemotherapie en/of radiotherapie en voor sommige patiënten, cryopreservatie van eicellen of embryo's is geen optie. Als alternatief, een groeiend aantal van deze patiënten kiezen om te cryopreserve van eierstokweefsel voor autograft na invordering en kwijtschelding. Ondanks verbeteringen in de resultaten onder patiënten die een auto-transplantatie cryopreserved eierstokweefsel, blijft efficiënte revascularisatie geënte weefsel een obstakel. Om te verzachten ischemie en dus resultaten in patiënten die een auto-transplantatie te verbeteren, ontwikkelden we een vasculaire cel-gebaseerde strategie om perfusie van eierstokweefsel te versnellen. Met cryopreserved ovariaal weefsel in een muismodel van xenograft beschrijven we een methode voor co transplantatie van exogene endotheliale cellen (ExECs). We breiden deze aanpak om ExECs die zijn ontworpen om te constitutively express Anti-Mullerian hormone (AMH), waardoor de aanhoudende paracrine signalering input voor ovariële transplantaten tewerk te stellen. Co transplantatie met ExECs verhoogd folliculaire volume en verbeterde follikelgroei follikel ontwikkeling en AMH-uiten ExECs bevorderd eigendomsvoorbehoud rustige primordiale follikels. Deze gecombineerde strategie kan een nuttig instrument voor beperkende ischemie en modulerende folliculaire activering in het kader van het behoud van de vruchtbaarheid en/of onvruchtbaarheid bij groot worden.

Om te bepalen of mede transplantatie van ExECs voorziet in een uitkering aan patiënten weefsel, werden ontdooide ovariële corticale strips verdeeld in gelijke grootte stukken en bilateraal geaccepteerd in immuno-gecompromitteerd, knik scid gamma (NSG), muizen. Met één kant ingebed in een fibrine clot alleen (geen ECs) en de andere met ExECs (Figuur 1a), diende elke muis als haar eigen controle. ExECs werden verkregen via isolatie van primaire endotheel va...

Co-transplantation of Human Ovarian Tissue with Engineered Endothelial Cells: A Cell-based Strategy Combining Accelerated Perfusion with Direct Paracrine Delivery

Voor sommige patiënten is de enige optie voor behoud van de vruchtbaarheid cryopreservatie van eierstokweefsel. Helaas ondermijnt vertraagde revascularisatie folliculaire levensvatbaarheid. Hier presenteren we een protocol om mede de transplantatie van menselijke eierstokweefsel met endotheliale cellen voor gebruik als een cel-gebaseerde strategie combineren versnelde perfusie met een directe paracrine levering van biologische actieve moleculen.
