Den kvindelige reproduktive menstruationscyklus er karakteriseret ved en stigning i progesteron niveauer i hele den luteale fase, dermed inducere decidualization af ESC i runde, epithelial-lignende sekretoriske celler3,8. Indledningen af decidualization er arter afhængige. Hos mennesker opstår decidualization spontant på stigningen i progesteron koncentrationen, mus kraever blastocyst tilstedeværelse10,11</...

Mellem stadier af første menstruation og overgangsalder undergår kvinder i den fødedygtige alder månedlige cyklusser af hormon-regulerede endometrie spredning, differentiering og efterfølgende afgivelse i forberedelse til graviditet i en proces kendt som menstruation1 ,2. Sådanne fysiske ændringer af den menneskelige endometriet er nødvendige for korrekt embryo implantering i livmodervæggen1. Ændringer i endometriet, herunder morfologiske og biokemiske tilpasninger, er medieret gennem hele menstruationscyklus via æggestokkene steroid hormoner østrogen og progesteron (P4)3,4,5. Inden for den proliferative (eller follikulært) fase, preovulatory østrogen niveauer stigning, iværksætte endometriet fortykkelse. Efter ægløsning fremmer den sekretoriske (eller luteal) fase en betydelig stigning i P4 koncentrationer, inducerende morfologiske omdannelsen af endometrie stromale celler (ESC) fra fibroblast-lignende udseende til afrundet, epithelial-lignende decidual celler i en proces kendt som decidualization4,6. Forkert decidualization er blevet oprettet som en grundlæggende årsag til implantation fiasko og efterfølgende tidlig embryo abort4,7,8. Derfor er forstå de molekylære mekanismer bag decidualization fordelagtig for diagnosticering og behandling af tidlig graviditet tab.
I øjeblikket er flere metoder udnyttet til at udforske underliggende virkningerne af decidualization på endometrie stromale celler. In vivo, mus livmoderen kan fremkaldes kunstigt for decidualization via mekaniske stimulation (dvs., skrabe) eller olie injektion i en hormonrelaterede PRIMES livmoderen9. Adskilt fra mennesker, denne syntetiske stimulation fremmer differentiering af uterin lumen ved at give udseende af blastocyst tilstedeværelse, et skridt, der er nødvendig for indledningen af decidualization i gnavere10,11. Derfor, på grund af translationel komplikationer forbundet med dyremodeller og de etiske dilemmaer omkring i vivo baseret undersøgelser hos mennesker, decidualization baserede modeller er mest held studerede in vitro-.
I denne undersøgelse rekrutteres emner gennem placeringen af reklamer i både engelsk og spansk Lokalaviser. Emner identificeret som egnede kandidater til denne undersøgelse er bragt at mødes med koordinatoren for forskning, som en fuld offentliggørelse af potentielle risici diskuteres. Efter bekræftelse af en komplet forståelse af potentielle risici, er registreredes samtykke opnået i både skriftlige og mundtlige former. Emnet samtykke omfatter tilladelse til (1) gennemgå tapning (2) på langtidsopbevaring af deres væv for fremtidig forskning og (3) tilslutter sig oprettelsen af primære kulturer fra enheder, der opsamlet væv. Efter samtykke får emner en form for at fuldføre i som tilladt selv-identifikation af race/Etnicitet og/eller ret til hemmeligholdelse. Et efterfølgende besøg er planlagt til at nå endometriet biopsi baseret på motivets menstruationscyklus. Volontører rekrutteret til undersøgelsen afspejler både etniske og racemæssige demografi af St. Louis metropolitan region, som dokumenteret af folketællingen i 2012 og indebærer ikke deltagelse af alle sårbare befolkning, herunder gravide kvinder, fostre, embryoer, børn under 18 år af alder eller andre sårbare grupper. Krav for deltagelse i biopsi prøve samling omfatter (1) at være i alderen 18-45 år (2) der har regelmæssig menstruationscyklus (25-32 dage) (3) har ingen aktuelle graviditet eller brug af hormonel/intrauterin enhed prævention for 30 dage før tilmelding (4) har ingen aktuelle vaginal infektion eller seksuelt overførte sygdomme (5) har ingen aktuelle antibiotika behandlinger, og (6), hvis ingen aktuelle unormal celleprøve.
Inden for denne undersøgelse, menneskelige endometrie stromale celler (menneskelige Stamceller) kulturperler og kunstigt fremkaldt til undergår in vitro- decidualization gennem tilskud af hormoner (estradiol (E2), medroxyprogesteronacetat (MPA) og cyklisk adenosin monophosphate (cAMP)) til medium. I denne metode ændres graden af decidualization baseret på det samlede antal dage af hormonel behandling. I forbindelse med cytoskeletal omlejring inducerer hormonel supplering biokemiske tilpasninger, hvor de decidual celler opleve sekretoriske-lignende kvaliteter2,4. Udtryk af hallmark gener, som prolaktin (PRL) og insulin-lignende vækstfaktor bindende protein 1 (IGFBP1), kan udnyttes til at bekræfte og kvantificere graden af menneskelige Stamceller decidualization5,12, 13 , 14. vigtigere, levedygtigheden af denne protokol til at foretage genet specifikke knockdown fremgår også.

isolation of human endometrial stromal cells for in vitro decidualization

Differentiering af humane endometrie stromale celler (menneskelige Stamceller) fra fibroblast-lignende udseende til sekretoriske decidua er en transformation, der kræves til embryo implantering i livmoderslimhinden mødre livmoderen. Forkert decidualization er blevet oprettet som en grundlæggende årsag til implantation fiasko og efterfølgende tidlig embryo abort. Derfor er forstå de molekylære mekanismer bag decidualization en fordel at forbedre hastigheden af vellykkede fødsler. In vivo baseret undersøgelser af kunstige decidualization er ofte begrænsende på grund af etiske dilemmaer forbundet med human forskning samt translationel komplikationer i dyremodeller. Som et resultat, er in vitro- assays gennem primære cellekultur ofte udnyttet til at udforske graduering af decidualization via hormoner. Denne undersøgelse giver en detaljeret protokol for isolering af menneskelige Stamceller og efterfølgende kunstige decidualization via tilskud af hormoner til dyrkningsbaserede medium. Yderligere, denne undersøgelse giver et veldesignet metode til knockdown enhver gen af interesse ved at udnytte lipid-baserede siRNA transfections. Denne protokol tillader optimering af kultur renhed samt produkt udbytte, hvilket maksimerer muligheden for at udnytte denne model som en pålidelig metode til at forstå de molekylære mekanismer bag decidualization, og den efterfølgende kvantificering af udskilles agenter af decidualized endometrie stromale celler.

Decidualization i menneskelige Stamceller kultur
Efter isolering, menneskelige endometrie stromale celler blev kultiveret til en éncellelag dannelse med 80-90% confluency og induceret for in vitro- decidualization ved at behandle med 10 nM E2, 1 µM MPA og 50 µM cAMP (EPC). Morfologiske ændringer forbundet med in vitro- decidualization blev visualiseret i figur 1A</stron...
