Neuromics' FGF-2 for Expanding Human Cells

FGF-2 and Fibrochondrocytes

FGF-2 of FGF-basic is an important a growth factor for many cell-based assays. Neuromics' has rock solid FGFs for supplementing media used to grow cells. Check out publications referencing use of FGF-2.

Here's the latest publication: Yan Liang, Enaam Idrees, Stephen H. J. Andrews, Kirollos Labib, Alexander Szojka, Melanie Kunze, Andrea D. Burbank, Aillette Mulet-Sierra, Nadr M. Jomha & Adetola B. Adesida. Plasticity of Human Meniscus Fibrochondrocytes: A Study on Effects of Mitotic Divisions and Oxygen Tension. Scientific Reports 7, Article number: 12148 (2017) doi:10.1038/s41598-017-12096-x. ...Thereafter the number of viable MFCs were counted using a haemacytometer after trypan blue staining. MFCs were plated at 104 cells/cm2 and cultured in the standard medium described above supplemented with FGF-2 (5 ng/mL; Neuromics, MN, USA, Catalog#: PR80001) and TGFβ1 (1 ng/mL; ProSpec, NJ, USA, Catalog#: cyt-716) under normal oxygen tension (21% O2) at 37 °C in a humidified incubator...

Blue (DAPI): cells, Red (Texas Red): collagen I, Green (FITC): collagen II. (A) Pellets cultured under NRX, (B) Pellets cultured under HYP from four passages. Scale bar: 100 µm
Our ISO-Kine FGF-2 is especially potent as it virtually endotoxin free.

Culturing Stem Cells in 3-D

Requires Potent Media + Supplements

Neuromics is responding to the many challenges our clients face in building 3-D, in-vivo like, cell- based assays. We do this by offering the most potent Media plus Supplements like FGFS.

Here's a protocol for single cell 3-D assays using hMSCs and Hydrogels. It features use of our ISOKineTM FGF


Images: Cell-centering in cytocompatible microgels enables long-term single-cell 3D culture by preventing cell escape. a) Qualification of Dex-TA microgel crosslinking as a function of the microemulsion flow rate (Qemulsion) and concentration of the H2O2 feed ([H2O2]feed). Blue, green, and red indicate incomplete crosslinking, complete crosslinking, and H2O2 excess, respectively. b,c) Amplex Red assay to quantify the concentration of residual H2O2 ([H2O2]emulsion) in Dex-TA microgel precursor droplets and crosslinked microgels after their retrieval from the diffusion-based crosslinking platform. d) The microencapsulation procedure had no detrimental effect on short-term cell survival. e) Delayed crosslinking resulted in 4 ± 1% cell escape after 7 d of in vitro culture, as compared to 27 ± 5% cell escape when using coupled emulsification and gelation. f) The number of encapsulated cells per microgel tightly followed the Poisson distribution and remained similar throughout long-term (28 d) of in vitro culture, which confirmed that cell centering prevents cell escape. g–i) MSCs encapsulated in delayed enzymatically crosslinked microgels remained viable and metabolically active throughout 28 d of in vitro culture. j) Positive Oil Red O and k) Alizarin Red staining confirmed that l) more than 60% of the microencapsulated MSCs could differentiate into the adipogenic and osteogenic lineage, respectively. Black scale bars: 50 µm, white scale bars: 5 µm. DOI: 10.1002/smll.20160371.

Protocol for Cell Isolation and Expansion: Human MSCs were isolated from fresh bone marrow samples and cultured as previously described. The use of patient material was approved by the local ethical committee of the Medisch Spectrum Twente and informed written consent was obtained for all samples. In short, nucleated cells in the bone marrow aspirates were counted, seeded in tissue culture flasks at a density of 500 000 cells cm−2, and cultured in MSC proliferation medium, consisting of 10% FBS, 100 U mL−1 penicillin, 100 mg mL−1 streptomycin, 1% GlutaMAX, 0.2 × 10−3 m ascorbic acid, and 1 ng mL−1 bFGF (added fresh) in αMEM. Mouse insulinoma MIN6-B1 cells (provided by Dr. P. Halban, University Medical Center, Geneva, Switzerland) were cultured in MIN6 proliferation medium, consisting of 10% (v/v) FBS, 100 U mL−1 penicillin, and 100 mg mL−1 streptomycin, and 71 × 10−6 m 2-mercaptoethanol (added fresh) in DMEM. When cells reached near confluence, the cells were detached using 0.25% Trypsin-EDTA at 37 °C and subsequently subcultured or used for experimentation.

The Power of ISOkine Stem Cell Growth Factors

What Endotoxin, Animal and Serum Free Means to You

ISOkine™ growth factors are produced in barley, bypassing the use of bacterial or animal cell systems.

Why Does this Matter? Proteins produced in bacterial systems contain trace Endotoxins (toxins produced by the bacterial hosts). Studies show that these Endotoxins can compromise health of your stem cell based assays. Animal and human cell expression systems pose risk to your assays, because they may harbor pathogens.


They are Low Cost and Work in the Hands of our Customers: "The ISOKine mouse LIF is an excellent product! I enjoyed dealing with Neuromics. My interactions with Brett were very professional and he assured me the product was guaranteed to work; which it did." Andy Babwah, Children’s Health Research Institute

100% Animal Free FGF Basic

New ISO-kineTM FGF basic-only 39 USD-10 ug.

Fibroblast Growth Factor (FGF) Recombinant Proteins are widely used as tools in Stem Cell Research. They have the capabilities to catalyze growth and differentation as well as maintain cell stasis. We continue to offer new FGFs to make sure we meet the unique demands of our cutsomers and collaborators  .

Our E. Coli derived Human FGF (146 aa) recombinant protein is our #1 seller. As Stem Cell research moves from the bench top to the bedside, there will be a growing need for 100% animal free proteins. We are please to announce we have added a 100% animal free FGF (146 aa) basic that has bio-activity comparable to our top selling options

I anticipate offering more ISOKineTM Bio-risk free Stem Cell Research growth factors to meet growing demand. This growth will be driven by their unique advantages. These include low protease activity and secondary metabolite content and simple protein content all of which aid in downstream processing. These products also have the G.R.A.S. (Generally Recognised As Safe) status from FDA.
