2. Peripheral Blood Stem Cell Collection
Peripheral blood stem cell collection is a non-surgical method of extracting stem cells from the bloodstream. The patient’s blood is treated with medication to stimulate the production and release of stem cells from the bone marrow into the bloodstream. The stem cells are then collected using a process called apheresis, where blood is passed through a machine that separates the stem cells from other blood components. This method is commonly used in the treatment of certain cancers and blood disorders.
3. Umbilical Cord Blood Collection
Umbilical cord blood collection involves the extraction of stem cells from the umbilical cord and placenta after childbirth. This method is non-invasive and painless, as the stem cells are collected from the umbilical cord blood, which is typically discarded after delivery. The collected cord blood is then processed and stored in stem cell banks for future therapeutic use. Umbilical cord blood stem cells have been used in the treatment of various blood disorders and immune system diseases.
4. Adipose Tissue Extraction
Adipose tissue extraction, also known as liposuction, involves the extraction of stem cells from fat tissue. This method is less invasive compared to bone marrow aspiration and can yield a higher number of stem cells. Adipose tissue is usually extracted from the abdomen or thigh using a small cannula. The extracted fat tissue is processed to isolate the stem cells, which can then be cultured and expanded for therapeutic purposes. Adipose-derived stem cells have shown promise in regenerative medicine and cosmetic applications.
5. Amniotic Fluid Extraction
Amniotic fluid extraction involves the collection of stem cells from the amniotic fluid surrounding the fetus during pregnancy. This method is typically performed during prenatal testing, such as amniocentesis. The amniotic fluid contains a variety of stem cells, including embryonic-like stem cells and mesenchymal stem cells. These stem cells can be isolated, cultured, and used for various research and therapeutic purposes.
6. Embryonic Stem Cell Extraction
Embryonic stem cell extraction involves the extraction of stem cells from early-stage embryos, typically obtained from fertility clinics or donated embryos.

Processing and Culture of Stem Cells in Malaysia
Once stem cells are extracted, they undergo a series of processing and culture techniques to ensure their viability and quality. These techniques include:
1. Isolation and Purification of Stem Cells
After extraction, stem cells must be isolated and purified from other cells and contaminants. This is typically done through a process called centrifugation, where the stem cells are separated based on their density. The isolated stem cells are then further purified using specific markers or antibodies that target stem cell-specific proteins on their surface. This ensures that only the desired stem cells are used for further processing and culture.
2. Expansion and Propagation of Stem Cells
Once isolated and purified, stem cells are cultured in a controlled environment to promote their growth and expansion. This is typically done in specialized culture dishes or bioreactors that provide the necessary nutrients and growth factors for the stem cells. The culture conditions, such as temperature, oxygen levels, and pH, are carefully regulated to mimic the natural environment required for stem cell growth. Over time, the stem cells multiply and form colonies, increasing their numbers for therapeutic use.
