We presenteren in dit artikel een nieuw strekken platform dat kan worden gebruikt om cel responsen op complexe anisotrope biaxiale mechanische vervorming onderzoeken en kwantificeren van de mechanische eigenschappen van biologisch weefsel.

A Novel Stretching platform voor toepassingen in de Cel en Weefsel Mechanobiology

Wij rapporteren een inrichting en een nieuwe werkwijze om cellen en embryo bestuderen. Enkele cellen worden nauwkeurig gerangschikt in microcavity arrays. Hun 3D opsluiting is een stap in de richting 3D-omgevingen aangetroffen in fysiologische omstandigheden en maakt het organel oriëntatie. Door het regelen van celvorm, deze opstelling minimaliseert variatie gerapporteerd in standaardtesten.

Het bestellen van enkele cellen en Single Embryo&#39;s in 3D Opsluiting: een nieuw apparaat voor High Content Screening

Er werd een nieuw beeldvormingsprotocol ontwikkeld met behulp van een op maat gemaakte motorgestuurde mechanische actuator om de meting van realtime-responsen op mechanische spanning in levende cellen mogelijk te maken. Relevant voor mechanobiologie, kan het systeem spanningen tot 20% toepassen terwijl het realtime beeldvorming met confocale of atomaire krachtmicroscopie mogelijk maakt.

Live cell imaging tijdens Mechanical Stretch

Met behulp van een eerder ontworpen apparaat om mechanische belasting toe te passen op aanhangende cellen, dit document beschrijft een vernieuwde substratum geometrie en een aangepaste apparaat voor hoge-resolutie single-cell beeldvorming van gespannen cellen met een 100x olie onderdompeling doelstelling.

Hoge-resolutie beeldvorming van kern dynamiek in levende cellen onder Éénassige trekspanning

De gepresenteerde methode omvat het uniaxiaal uitrekken van 3D zachte hydrogels ingebed in siliconenrubber terwijl live confocale microscopie mogelijk is. Karakterisering van de externe en interne hydrogelstammen en vezeluitlijning worden gedemonstreerd. Het ontwikkelde apparaat en protocol kunnen de reactie van cellen op verschillende stamregimes beoordelen.

Gecontroleerde stam van 3D-hydrogels onder live microscopiebeeldvorming

Dit werk presenteert een flexibel protocol voor het gebruik van fluorescerend gelabelde elastomeer contracteerbare oppervlakken (FLECS) -technologie in microwell-formaat voor vereenvoudigde, hands-off kwantificering van contractiele krachten met één cel op basis van gevisualiseerde verplaatsingen van fluorescerende eiwitmicropatronen.

Vereenvoudigde, high-throughput analyse van eencellige contractiliteit met behulp van microgepatterde elastomeren

Hier presenteren we een veelzijdig equibiaxiaal rekapparaat dat pneumatisch wordt bediend en compatibel is met microscopie met hoge resolutie.

Equibiaxiaal rekapparaat voor sterk vergrote live-cell confocale fluorescentiemicroscopie

In veel biologische en klinische situaties is het voordelig om cellulaire processen te bestuderen als ze zich ontwikkelen in hun eigen micro-omgeving. Hier beschrijven we de montage en het gebruik van een low-cost fiber-optische microscoop, die real-time beeldvorming kan bieden in celkweek, dierproeven en klinische studies de patiënt.

Hoge-resolutie Fiber-optic Microendoscopy voor In situ Cellular Imaging

Dit protocol zal de extractie en analyse van vrije en geësterde bioactieve vetzuren uit cellen demonstreren. Vetzuren worden nauwkeurig gekwantificeerd met behulp van stabiele isotoopverdunning, chirale vloeistofchromatografie, electronenvangst-atmosferische chemische ionisatie-meervoudige reactiebewaking massaspectrometrie (SID-LC-ECAPCI-MRM/MS).

Drosophila larven zijn een aantrekkelijk model systeem voor live-imaging vanwege hun doorschijnende cuticula en krachtige genetica. Dit protocol beschrijft hoe u een single-layer PDMS apparaat, genaamd de 'larve chip' voor live-beeldvorming van cellulaire processen binnen neuronen van 3 e instar Drosophila larven benutten.
