Most cited protocols related to «Embryoid Bodies»

Embryoid bodies were generated from hiPSCs and then transferred to nonadherent plates (Corning). Colonies were maintained in suspension in N2 media (DMEM/F12 (Invitrogen), 1x N2 (Invitrogen)) for 7 days and then plated onto polyornithine (PORN)/Laminin-coated plates. Visible rosettes formed within 1 week and were manually dissected and cultured in NPC media (DMEM/F12, 1x N2, 1x B27-RA (Invitrogen), 1 µg/ml Laminin (Invitrogen) and 20 ng/ml FGF2 (Invitrogen). NPCs are maintained at high density, grown on PORN/Laminin-coated plates in NPC media and split approximately 1:4 every week with Accutase (Millipore). For neural differentiations, NPCs were dissociated with Accutase and plated at low density in neural differentiation media (DMEM/F12-Glutamax, 1x N2, 1x B27-RA, 20 ng/ml BDNF (Peprotech), 20 ng/ml GDNF (Peprotech), 1 mm dibutyrl-cyclicAMP (Sigma), 200 nM ascorbic acid (Sigma) onto PORN/Laminin-coated plates.
Assays for neuronal connectivity, neurite outgrowth, synaptic protein expression, synaptic density, electrophysiology, spontaneous calcium transient imaging and gene expression were used to compare control and SCZD hiPSC neurons.

The protocol is illustrated in Extended Data Fig. 2a. Specifically, iPS cell colonies were detached from the feeder layer with 1 mg ml−1 collagenase treatment for 1h and suspended in embryoid body (EB) medium, consisting of FGF-2-free iPS cell medium supplemented with 2 μM dorsomorphin and 2 μM A-83, in non-treated polystyrene plates for 4 days with a daily medium change. After 4 days, EB medium was replaced by neural induction medium (hNPC medium) consisting of DMEM/F12, N2 supplement, NEAA, 2mg ml−1 heparin and 2 μM cyclopamine. The floating EBs were then transferred to Matrigel-coated 6-well plates at day 7 to form neural tube-like rosettes. The attached rosettes were kept for 15days with hNPC medium change every other day. On day 22, the rosettes were picked mechanically and transferred to low attachment plates (Corning) in hNPC medium containing B27. For neuronal differentiation, resuspended neural progenitor spheres were dissociated with Accutase at 37°C for 10 min and placed onto poly-D-lysine/laminin-coated coverslips in the neuronal culture medium, consisting of Neurobasal medium supplemented with 2 mM L-glutamine, B27, 10 ng ml−1 BDNF and 10 ng ml−1 GDNF. Half of the medium was replaced once a week during continuous culturing. For electrophysiological recordings, neural progenitors were plated on a confluent layer of rodent astrocytes as previously described21 (link),34 (link). These cultures exhibited similar neuronal densities and parallel cultures were used for recordings of different iPS cell lines in a blind fashion.

For spheroid generation, 200 μl/well of cell suspensions at optimized densities (0.5 × 104 cells/ml for U-87 MG, KNS42 and LICR-LON-HN4; 1.5 × 104 for MDA-MB-231 P and M variants) were dispensed into ULA 96-well round-bottomed plates (Corning B.V. Life Sciences, Amsterdam, The Netherlands) using a multichannel pipette. Plates were incubated for 4 days at 37°C, 5% CO2, 95% humidity. Where indicated, optimal three-dimensional structures were achieved by addition of 2.5% Matrigel as previously described [52 (link)]. Fully automated image analysis of tumor spheroids was carried out on a Celigo cytometer (Cyntellect Inc, San Diego, CA, USA; http://www.cyntellect.com/content/products/celigo/index.html), which is equipped with a 4-megapixel CCD camera with an F-theta scan lens (1 μm/pixel, 0.25 NA, 3.5 ×). Images were acquired and analyzed by using the Colony Counting Embryoid Body application with the option to scan 1/16 field of view/well. The width of 1 field of view (FOV) is 975 pixels/2,057 μm and image file size is 0.41 MB. Further technical details of imaging parameters are shown in Additional file 15.
For the lower throughput method, images were captured using an inverted microscope (Olympus IX 70, (Olympus Microscopy, Southend-on-SeaEssex, UK) equipped with a CCD camera (QImaging, Surrey, BC, Canada and imported into Image-Pro Plus Analyzer software (Media Cybernetics, Inc., Bethesda, MD, USA; http://www.mediacy.com/index.aspx?page=IPP) and by either using macros or manually, multiparametric analysis was performed. In both cases, the radius of each tumor spheroid was used to calculate the volume (μm3): V = 4/3 π r3.
For comparison with our system, U-87 MG cells were also used to generate spheroids using conventional methods as follows: (1) agar-coated 96-well flat-bottomed plates (BD Biosciences, Oxford, England) as previously described [26 (link)] (0.5 × 104 cells/ml as in the ULA 96-well round-bottomed plates); (2) poly-Hema-coated 24-well plates (2 × 105 cells/ml, 1 ml/well). A stock solution of 6 mg/ml poly-Hema (Sigma-Aldrich Company Ltd., Dorset, England) in 95% ethanol was prepared and diluted 1:10 in ethanol. A total of 100 μl/well was dispensed and left to dry before cell addition; (3) RCCS (105 cells/ml, 10 ml/disposable vessel).
In all cases, an inverted microscope was used for image analysis as described above.

A vector, pCAG2LMKOSimO, which have c-Myc, Klf4, Oct4 and Sox2 coding regions linked with 2A peptide sequences driven by CAG enhancer/promoter18 (link),21 (link), were constructed as described in the Methods. The vectors were introduced into MEFs using Nucleofector II (Amaxa) and cells were cultured in ES cell culture condition for up to 4 weeks. Colonies showing ES cell-like morphology were picked and cultured either on irradiated MEFs (γMEFs) or gelatin after trypsinization. Gene expression, integration number/sites of the vector in the established cell lines were analyzed by quantitative PCR, immunoblotting, Southern blotting and inverse PCR, respectively. The reprogramming cassette was excised by Cre transient transfection in the presence or absence of an Fgf receptor inhibitor PD173074 (100 ng/ml), and pluripotency of the cell lines were examined in vitro (embryoid body formation, neural differentiation) and in vivo (teratoma formation, blastocyst injection).

The lower bodies of E18.5 mouse embryos were fixed with 4% paraformaldehyde (PFA) at 4 °C overnight. Fixed samples were further processed using a Tissue-Tek VIP-VI automatic infiltration processor (Sakura Finetek, Tokyo, Japan) with a standard 19 h program, followed by transfer into moulds. The samples were subsequently embedded with paraffin wax and sectioned perpendicularly against the head–tail axis using a microtome (RM2125RT, Leica, Wetzlar, Germany) set at a thickness of 4 μm. Sectioned tissues were mounted on New Silane II coated glass slides (Muto Pure Chemicals, Tokyo, Japan) and incubated on a paraffin extension plate (Leica) at 45 °C overnight. Post deparaffinization, slides were soaked in Mayer’s haematoxylin solution for 10 min followed by washing with water for 20 min. Slides were then incubated in 1% Eosin Y solution for 5 min before visualization under an all-in-one microscope BZ-9000 (Keyence, Osaka, Japan).

Seven different iPSCs, two different clones of two healthy controls (CONTROL 1 and CONTROL 2), two clones of THDA (THDA1#5 and THDA1#17), two clones of THDB (THDB1#1 and THDB1#15), and one isogenic (isoTHDA1#17), were differentiated into dopaminergic neurons using a 30‐day protocol based on DAn patterning factors and co‐culture with mouse PA6 feeding cells to provide trophic factor support, with minor modifications (Sánchez‐Danés et al, 2012 (link)). Specifically, iPSCs were cultured in mTeSR commercial medium until they reached 80% confluence and then mechanically aggregated to form embryoid bodies (EBs), without using lentiviral vectors to express LMX1A transcriptional factor. EBs were cultured for 10 days in suspension in N2B27 medium, consisting of DMEM/F12 medium (GIBCO), neurobasal medium (GIBCO), 0.5× B27 supplement (GIBCO), 0.5× N2 supplement (GIBCO), 2 mM ultraglutamine (Lonza) and penicillin–streptomycin (Lonza). In this step, N2B27 was supplemented with SHH (100 ng/ml, Peprotech), FGF‐8 (100 ng/ml, Peprotech), and bFGF (10 ng/ml; Peprotech). Neural progenitor cells (NPCs) were then seeded on top of PA6 for 21 days in N2B27 medium, as described (Sánchez‐Danés et al, 2012 (link)). Studied cultures were fixed with PFA 4% and characterized for dopaminergic specificity and for cell morphology.

iNIL stem cells were generously provided by Dr Esteban Mazzoni (New York University) and maintained in the 2i‐based media (Table S3) containing leukemia inhibitory factor (ESG1106; Millipore), CHIR99021 (NC0664823; Fisher Scientific, Hanover Park, IL, USA), and PD0325901 (NC0759248; Fisher Scientific). To differentiate iNIL cells into motor neurons, cells were lifted using TrypLE (12‐604‐021; Fisher) and feeder media (Table S4), seeded to a suspension culture dish (08‐772‐32; Fisher) in AK media (Table S5) [37 ], and incubated for 2 days to allow the embryoid body formation. Doxycycline was added to the suspension culture to induce the expression of three transcription factors, neurogenin‐2, islet‐1, and lhx‐3. These three transcription factors drive neuronal specification in the embryoid body. Two days later, cells were dissociated from the embryoid body using a standard approach, and the dissociated cells were resuspended in the motor neuron media cocktail containing neurotrophic factors (GDNF, BDNF, and CNTF; Table S6). The resuspended cells were plated on poly‐l‐ornithine (PLO)‐coated plates and incubated for 2 days for motor neuron maturation. The drugs were treated to the motor neuron culture at this stage. A more detailed protocol with media recipe for creating motor neurons from iNIL stem cell was described previously [32 (link)]. The file Appendix S1 contains tables that show all culture reagents with working concentrations.

Retinal differentiation was performed with modifications for GMP-compliance as described previously [31 (link), 50 (link)]. IPSCs were cultured on laminin 521 coated plates in E8 medium. Embryoid bodies (EBs) were lifted with ReLeSR (STEMCELL Technologies, Cambridge, MA) and transitioned from E8 to neural induction medium (NIM- DMEM / F12 (1:1), 1% N2 supplement, 1% non-essential amino acids, 1% Glutamax (Thermo Fisher Scientific), 2 µg / mL heparin (Sigma-Aldrich, St. Louis MO) and Primocin (InvivoGen, San Diego, CA)) over a four-day period. On day 6, NIM was supplemented with 1.5 nM BMP4 (R&D Systems, Minneapolis, MN). On day 7, EBs were adhered to Maxgel coated plates (Sigma-Aldrich). BMP4 was gradually transitioned out of the NIM over seven days. On day 16, the media was changed to retinal differentiation medium (RDM - DMEM / F12 (3:1), 2% B27 supplement (Thermo Fisher Scientific), 1% non-essential amino acids, 1% Glutamax and 0.2% Primocin). On day 25–30 the entire EB outgrowth was mechanically lifted using a cell scraper and transferred to ultra-low attachment flasks in 3D-RDM (RDM plus 10% KnockOut serum replacement (KSR); Thermo Fisher Scientific), 100 µM taurine (Sigma-Aldrich), 1:1000 chemically defined lipid concentrate (Thermo Fisher Scientific), and 1 µM all-trans retinoic acid (until day 100; Sigma-Aldrich). The cells were fed three times per week with 3D-RDM until harvest.
