Descriptions：R-spondin 1 (RSPO1, Roof plate-specific Spondin 1) is a cysteine-rich secreted glycoprotein that belongs to the R-Spondin family. Structurally, R-spondin 1 harbors an N-terminal signal peptide, two cysteine-rich furin-like (FU1-FU2) domains, a thrombospondin (TSP) domain, and a basic amino acid-rich (BR) C-terminal domain. R-spondin 1 acts as a ligand for the leucine-rich repeat-containing G-protein coupled receptor (LGR) family (LGR4/5/6), subsequent clearing negative regulators ZNRF3/RNF43 from the membrane, leading to the availability of Wnt receptor and activating Wnt/β-catenin signaling. The signal cascade is essential for regulating stem cell proliferation, embryonic development, and tissue homeostasis.

Descriptions：IL-5 is a 45-60 kDa homodimer cytokine that functions principally in the eosinophil arm of the Th2 response. It is a member of the helical bundle family of cytokines, along with IL-3, IL-4, and granulocyte-macrophage colony-stimulating factor (GM-CSF).

Descriptions：Interleukin-36 gamma (IL-36γ) consists of 134 amino acids. IL-36γ is a member of the interleukin-1 cytokine family. It plays a significant role in immune responses, particularly in inflammatory reactions, which are essential for binding with interleukin-1 receptor and serves as receptor agonists, enabling cytokine activity and generating pro-inflammatory.

Descriptions：Human DKK-1 (Dickkopf related protein 1) is a secreted antagonist of Wnt/beta-Catenin signaling. It interacts with LRP-6, and internalized complexes of DKK-1/LRP-6/Kremen 2 can downregulate Wnt signaling. The balance between Wnt signaling and Human DKK-1 inhibition is critical for bone formation and homeostasis. In addition, Human DKK-1 can act as either a tumor suppressor or promoter of metastasis.

Descriptions：Interleukin-34 (IL-34) is a 30 kDa cytokine with 223 amino acid residues. IL-34 is a ligand of CSF-1R and secreted from CSF-1R expressing cells like myeloid cells, epithelial cells, endothelial cells, fibroblasts, and neurons. IL-34 mediates cell survival, proliferation, cytokine/chemokine expression, and migration via activating several signaling pathways. Moreover, it also plays a critical role in developing and maintaining the mononuclear phagocytic system.

Descriptions：Bone Morphogenetic Protein-11 (BMP-11), known as Growth differentiation factor 11 (GDF11), is an extracellular multifunctional signaling cytokine that is also a member of the TGFβ family. BMP-11 can bind with the TGFβ receptor and is involved in SMAD protein signal transduction. Moreover, it promotes the formation of blood vessels and nerves that can control anterior-posterior patterning.
