Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

729
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Hematopoiesis01:21

Hematopoiesis

8.1K
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

3.7K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Regulation of Hematopoietic Stem Cells

3.8K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.5K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Area of Science:

  • Hematology
  • Biotechnology
  • Data Science

Background:

  • Hematopoietic stem cell transplantation (HSCT) is a crucial treatment for hematologic malignancies.
  • Timely donor availability is critical for successful HSCT outcomes.
  • Predicting donor availability is a significant challenge in the HSCT process.

Purpose of the Study:

  • To develop and validate a machine learning (ML) model to predict stem cell donor availability.
  • To compare the performance of different ML algorithms for donor availability prediction.
  • To optimize the HSCT process by ensuring timely transplants.

Main Methods:

  • Retrospective collection of 10,258 verification typing requests from the British Bone Marrow Registry (BBMR) between 2013 and 2018.
  • Implementation and comparison of three ML algorithms: boosted decision trees (BDTs), logistic regression, and support vector machines.
  • Evaluation of algorithm performance using the area under the receiver operating characteristic curve (AUC).

Main Results:

  • Boosted decision trees (BDTs) demonstrated superior performance in predicting BBMR donor availability.
  • The BDT model achieved an AUC of 0.826 on a test cohort of 2052 records.
  • Machine learning accurately predicts donor availability, with high predictive power.

Conclusions:

  • Machine learning, specifically BDTs, can accurately predict stem cell donor availability for HSCT.
  • The proposed ML approach can aid in optimizing the HSCT process by identifying potential donors efficiently.
  • Accurate donor availability prediction ensures patients receive timely transplants, potentially improving outcomes for blood cancer and disorder patients.
