Description:
Interleukin 1 alpha (IL-1α) is a member of the IL-1 family and a dual-function cytokine. Both the unprocessed precursor and a processed IL-1α protein signal through IL-1 receptor type 1 (IL-1R1). Various cells, including keratinocytes, thymic epithelium, hepatocytes, endothelial cells, fibroblasts, and the epithelial cells of mucous membranes, have high levels of intracellular IL-1α precursor. The precursor is also expressed on the surface of monocytes and B lymphocytes (Netea <i>et al.</i>). IL-1α recruits infiltrating cells to a site of injury during necrosis and plays an important role during processes of sterile inflammation (Cohen <i>et al.</i>; Rider <i>et al.</i>). During hypoxia, IL-1α contributes to angiogenesis (Carmi <i>et al.</i>). Studies in mice show that IL-1α is produced by microglia-like cells after ischemic brain injury, which contributes to the inflammation (Luheshi <i>et al.</i>).

Description:
Bone morphogenetic protein 2 (BMP-2) is a member of the transforming growth factor beta (TGF-β) superfamily. BMP-2 is a disulfide-linked homodimer, acts as a ligand for complexes of type I and II BMP receptors, and primarily activates SMAD1/5/8 signaling (Nohe <i>et al.</i>). BMP-2 is a potent differentiation factor and directs human pluripotent stem cells (hPSCs) towards various cell types including extra-embryonic endoderm, mesenchymal cells, and chondrocytes (Pera <i>et al.</i>). Although BMP-2 expression is low in healthy cartilage, its expression is upregulated at the site of cartilage damage (Blaney Davidson <i>et al.</i>). BMP-2 induces bone and cartilage formation in vitro and is able to induce chondrogenesis in human mesenchymal stem cells (Schmitt <i>et al.</i>). This product is animal component-free.

Description:
Interleukin 31 (IL-31), a four-helix bundle inflammatory cytokine, belongs to the IL-6 cytokine family which includes IL-6, oncostatin M, leukemia inhibitory factor (LIF), and cardiotrophin-1 ( Dillon <i>et al.</i>). IL-31 signals through a heterodimer composed of IL-31RA (also known as gp130-like receptor or GPL) and the oncostatin-M receptor (OSMR), both of which are expressed on monocytes (Diveu <i>et al.</i>; Ghilardi <i>et al.</i>), epithelial cells (Ip <i>et al.</i>), and keratinocytes (Kato <i>et al.</i>). Signaling through the GPL/OSMR complex activates the JAK/STAT, RAS/ERK, and PI3K/AKT signaling pathways, resulting in the downstream activation of STAT1, STAT3, and STAT5 transcription factors (Cornelissen <i>et al.</i>; Dambacher <i>et al.</i>; Dillon <i>et al.</i>; Ip <i>et al.</i>). IL-31 responses have been associated with allergic responses and inflammatory skin diseases including atopic dermatitis (Cornelissen <i>et al.</i>; Gangemi <i>et al.</i>).

Description:
Granulocyte colony-stimulating factor (G-CSF) is a member of the CSF family of glycoproteins that regulate hematopoietic cell proliferation, differentiation, and function. It is a key cytokine involved in the production of neutrophils and the stimulation of granulocyte colony formation from hematopoietic progenitor cells (Metcalf and Nicola). G-CSF causes a range of effects including a transient reduction of SDF-1 expression (Petit <i>et al.</i>), the activation of metalloproteases that cleave VCAM-1 (Levesque <i>et al.</i>), and the release of norepinephrine from the sympathetic nervous system (Katayama <i>et al.</i>), leading to the release or mobilisation of hematopoietic stem cells from the bone marrow into the periphery. The G-CSF receptor is expressed on a variety of hematopoietic cells, including myeloid-committed progenitor cells, neutrophils, granulocytes, and monocytes. In addition to hematopoietic cells, G-CSF is also expressed in cardiomyocytes, neuronal cells, mesothelial cells, and endothelial cells. Binding of G-CSF to its receptor leads to activation of the JAK/STAT, MAPK, PI3K, and AKT signal transduction pathways. This product is animal component-free.

Description:
Transforming growth factor (TGF) beta 3 is a member of the TGF-β superfamily and regulates diverse cellular phenotypes. TGF-beta 3 binds to serine-threonine kinase type I and II receptors and activates signal transduction through SMAD2/3 proteins, thus regulating a variety of functions, including cell proliferation, differentiation, wound healing, apoptosis, and metabolism (Massagué; McDowell <i>et al.</i>). TGF-beta 3 enhances glycosaminoglycan production by mesenchymal stromal cells, stimulates scar-free healing, and improves glucose tolerance and phenotypic changes in adipocyte morphology (Hall <i>et al.</i>; Holton <i>et al.</i>). TGF-beta 3 induces proliferation of posterofrontal suture-derived mesenchymal stromal cells, and stimulates expression of fibroblast growth factors 2 and 18 (James <i>et al.</i>). This product is animal component-free.

Stimulating T cells with HHV6 (U90) Peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HHV6 (U90) Peptide pool is a lyophilised mixture of 267 peptides from protein U90 of human herpesvirus 6B (HHV-6B; strain Z29) and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 1078 on U90. U89 - U90 RNA expression occurs under immediate-early conditions of infection (Mirandola <i>et al.</i>), and the associated protein exhibits peri-nuclear and cytoplasmic localization (Nikolaou <i>et al.</i>). Also known as immediate-early protein IE1, latency-associated transcripts of HHV6 may function as a source of IE1 during viral reactivation (Kondo <i>et al.</i>). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Description:
Platelet-derived growth factor (PDGF) is a dimeric glycoprotein consisting of two disulfide bridge-stabilized polypeptide chains, A and B, which are assembled as heterodimers (PDGF-AB) or homodimers (PDGF-AA and PDGF-BB) (Fretto <i>et al.</i>; Westermark and Heldin). PDGF signals through the receptor tyrosine kinases PDGFRalpha and PDGFRbeta. It has been shown that PDGF-induced migration involves signaling pathways involving MEK/ERK, EGFR, Src, and PI3K/AKT (Kim <i>et al.</i>). PDGF is a potent mitogen for cells of mesenchymal origin, such as fibroblasts, glial cells, and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto <i>et al.</i>; Sachinidis <i>et al.</i>). It has been suggested that PDGF-AA is an important autocrine regulator of vascular endothelial growth factor (VEGF) expression in non-small cell lung carcinomas (Shikada <i>et al.</i>). PDGF-AA also mediates proliferation of oligodendrocyte progenitor cells and oligodendrocyte lineage differentiation through the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) (Hu <i>et al.</i>). PDGF-AA is commonly used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into oligodendrocyte precursor cells (Piao <i>et al.</i>).

Description:
Stimulating T cells with BKV (LT) Peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. BKV Peptide pool is a lyophilised mixture of 171 peptides from the Large T (LT) antigen of BK polyomavirus (BKV), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 695 on LT antigen. LT antigen is an early viral protein (Low <i>et al.</i>) that contributes to the transformation and maintenance of host cells (Nakshatri <i>et al.</i>). It has been found to bind to a subset of tumor suppressor proteins (Harris <i>et al.</i>), and its co-expression with p53 has been observed in polyomavirus-associated nephropathy (Seemayer <i>et al.</i>). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.
