Perspective on Death: A Gateway to a New Biology
Peter A Noble1, Alexander Pozhitkov2
1Department of Microbiology, University of Alabama, Birmingham, Alabama, USA.
Summary
Organismal death is not always irreversible. Postmortem cells can retain functionality and even form new structures, challenging traditional definitions of life and death.
Area of Science:
- Cellular Biology
- Postmortem Studies
- Organismal Death
Background:
- Traditional views define organismal death as irreversible cessation of integrated functioning.
- Organ donation highlights persistent functionality in organs, tissues, and cells postmortem.
- This persistence prompts investigation into the mechanisms of postmortem resilience.
Purpose of the Study:
- To explore the factors influencing postmortem cellular functionality and transformation.
- To challenge the established understanding of life and death boundaries.
- To investigate the potential for postmortem cells to form new multicellular entities.
Main Methods:
- Analysis of factors affecting postmortem cellular activity.
- Review of existing research on cellular resilience.
- Exploration of cellular transformation mechanisms postmortem.
Main Results:
- Postmortem cells exhibit varying degrees of functionality and transformation.
- Environmental conditions, metabolic activity, and survival mechanisms influence cellular fate.
- Certain cells demonstrate the capacity for growth and new multicellular formation.
Conclusions:
- Postmortem cellular functionality challenges the concept of irreversible death.
- Findings open new research avenues in biology and medicine.
- Understanding postmortem resilience enhances comprehension of life's complexity.

01:30Overview of Cell Death
7.0K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:21Kubler Ross's Stages of Dying
61
Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...

01:30Introduction to Biological Bases of Psychology
3.1K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

01:30Apoptosis
11.1K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

02:15Replicative Cell Senescence
3.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
