Summary
The Human Cell Atlas (HCA) is creating comprehensive human cell maps for health and disease research. This initiative prioritizes global diversity and community equity to ensure the atlas benefits all humanity.
Area of Science:
- Genomics
- Cell Biology
- Bioinformatics
- Human Health
Background:
- The Human Cell Atlas (HCA) is a global initiative aiming to map all human cells.
- Understanding cellular diversity is crucial for diagnosing, monitoring, and treating diseases.
- Previous atlases lacked comprehensive representation of global human populations.
Purpose of the Study:
- To outline the principles and action items for the Human Cell Atlas (HCA) commitment to equity.
- To ensure the HCA benefits all of humanity by including diverse populations.
- To foster a collaborative global partnership for creating comprehensive human cell reference maps.
Main Methods:
- Establishing principles for equitable data contribution and benefit sharing.
- Characterizing cells from diverse individuals globally.
- Developing comprehensive reference maps of human cells.
Main Results:
- The HCA has adopted principles and action items to affirm its commitment to equity.
- The atlas will characterize cells from diverse global individuals.
- The initiative aims to create a comprehensive resource for understanding human biology and disease.
Conclusions:
- The Human Cell Atlas (HCA) is committed to equity and global inclusivity.
- The atlas will serve as a foundational resource for human health research worldwide.
- Proactive consideration of community priorities ensures the HCA's broad benefit.

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

01:16Cell Lines
7.2K
A cell line is a population of cells grown in vitro that can be subcultured over several generations. Normal cells cease to divide after a certain number of cell divisions, a process known as replicative senescence. This number, called the Hayflick limit, was conceptualized by Leonard Hayflick in 1961 when he observed that fetal cells grown in culture could only divide 40-60 times. This limit is due to the shortening of the telomeres during each round of cell division, preventing cell division...

02:38Heterochromatin
11.2K
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at...

01:14Cell Adhesion in Plants
2.6K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

6.8K
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions take up more dye, appearing darker, while the less-compact areas take up less dye and appear lighter. Based on the compaction level, chromatins are classified into two primary forms – euchromatin and heterochromatin.
Euchromatin is the less dense region of the chromatin and stains lighter. Euchromatin contains histone H3 extensively...

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
