Handling procedures
- Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.- Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
- Culture medium
- DMEM (High Glucose) + 10% FBS
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.
Storage
- Shipped at conditions

Notes
Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.
Recommended control: Human wild-type HeLa cell line (Human wild-type HeLa cell line ab255448). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.

• Cells should be passaged when they have achieved 80-90% confluence.
• Do not allow the cell density to exceed 7x10E4 cells/cm2.
We will provide viable cells that proliferate on revival.

- Activity summary
Thrombospondin also known as TSP is a glycoprotein with a mass varying from 160 to 450 kDa depending on the form. It belongs to the extracellular matrix and is expressed in various tissues including endothelial cells platelets fibroblasts and the nervous system. Mechanically thrombospondin interacts with cell surface receptors matrix metalloproteinases and other matrix components to modulate cell-to-cell and cell-to-matrix communications. It functions through multiple domains that bind to several ligands influencing cellular processes such as adhesion migration and proliferation.
- Biological function summary
Thrombospondin influences angiogenesis immune response and cellular homeostasis. It is a part of the multi-protein complex in extracellular matrix and contributes to the regulation of tissue repair and development by inhibiting or stimulating new blood vessel formation as needed. Thrombospondin modulates the releasing of active transforming growth factor-beta (TGF-β) a critical factor in many biological functions. Through interacting with integrins and CD36 it regulates apoptosis and immune cell behavior.
- Pathways
Thrombogenic and angiogenic processes are heavily influenced by thrombospondin presence and activity. It plays a central role in the inhibition of the VEGF-induced angiogenesis pathway by competing with VEGF binding to endothelial cells. Furthermore thrombospondin is involved in TGF-β activation pathways by facilitating its release in a bioactive form. It interacts with other proteins like integrins and CD44 linking to pathways governing cell differentiation proliferation and tissue maintenance.
- Associated diseases and disorders
Thrombospondin links to cancer progression and cardiovascular abnormalities. In cancer it can function as both a tumor suppressor and promoter depending on the microenvironment influencing tumor angiogenesis and metastasis potential. It also connects to atherosclerosis where it affects vascular inflammation and plaque stability by interacting with proteins like fibronectin and collagen. These interactions highlight its potential as both a biomarker and therapeutic target in disease management.
