Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

1.2K
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...

Bone Cells and Tissue01:30

Bone Cells and Tissue

8.3K
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

Overview of Cell-Matrix Interactions

9.1K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Hepatic Portal System01:21

Hepatic Portal System

6.0K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

What are Cells?01:07

What are Cells?

200.7K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

14.9K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Area of Science:

  • Hematology
  • Genomics
  • Computational Biology

Background:

  • The Human Cell Atlas (HCA) aims to create comprehensive cell atlases for healthy and diseased states.
  • The hematopoietic system comprises diverse cell types, including poorly characterized transitional populations.

Purpose of the Study:

  • To molecularly define cell populations within the human bone marrow using HCA data.
  • To identify novel cell types, progenitor populations, and developmental trajectories in hematopoiesis.

Main Methods:

  • Analysis of over 100,000 hematopoietic cells from the HCA bone marrow project.
  • Application of advanced computational approaches to resolve cell populations and gene expression.
  • Identification of marker genes for cell classification and trajectory inference.

Main Results:

  • Resolution of 35 transcriptionally coherent hematopoietic cell groups, including rare and transitional types.
  • Discovery of novel mixed-lineage progenitor populations and inferred developmental trajectories.
  • Characterization of inter-donor variability in cell composition and gene expression, including age-related effects.

Conclusions:

  • The HCA bone marrow data provides an unprecedented molecular map of human hematopoiesis.
  • Novel insights into cell-type diversity, progenitor states, and developmental pathways are revealed.
  • An interactive platform facilitates exploration of these findings and aids cellular classification.
