The concept of cell adhesion arose from the work of Friedrich Daniel von Recklinghausen in 1862 while working on squamous epithelium. [7]
Egg jelly is a gelatinous layer that surrounds oocytes and releases species-specific chemoattractants that activate and guide sperm to the oocyte. [8] abbr
Developmental biology is the study of the processes and phenomena that give rise to and maintain mature organisms. Processes of particular interest include cell growth, cell differentiation, and morphogenesis.
While originally embryogenesis occupied most of the study of developmental biology, the past several decades have seen the scope of developmental biology broaden to include a variety of biological phenomena such as aging, regeneration, cancer, and metamorphosis.
One of the central processes that developmental biology explores is cell growth. Cell growth includes the division of cells to make more cells(cell proliferation), the enlargement of cells, the production of additional genetic material, as well as development of the extracellular matrix. In addition to stimulation and inhibition of these processes, regulation of cell growth also includes apoptosis, or programmed cell death. Inquiries into these processes underlie many fields of study. One such field is the emerging discipline of regenerative medicine which commonly studies the mechanisms by which certain organisms regrow lost body parts in hopes that application of this knowledge will lead to the development of techniques to regenerate lost or damaged organs in humans.
Probably the most fundamental question that developmental biologists seek to answer, however, is how does the body so precisely regulate cell growth? During human embryogenesis the fingers of the hands grow at opposite sides of the body, yet they end up nearly equal in length, and while the cells in the fingers are instructed to grow and divide, the cells that make up the webbing between the fingers are instead signaled to undergo apoptosis. While especially critical during embryogenesis, the regulation of cell growth and death remains important throughout an organism's life. Following birth, the outer layer of skin, the inner lining of the digestive tract, and even taste buds regularly slough off and get replaced by new cells. In its first year of life a human infant will replace nearly 100% of its skeleton with new skeletal tissue. [9] For a child between the ages of 8 and 14, approximately 20 billion to 30 billion cells undergo apoptosis daily, and for adults that number grows to 50-70 billion. [10]
If this tight balance of cell growth and cell death is disrupted then serious health issues can arise. A major example of this is cancer, which refers to a broad collection of diseases characterized by uncontrolled cell growth. Additionally, failure of the body to efficiently induce apoptosis in dying cells and subsequently remove them contributes to various autoimmune diseases by allowing the autoantigens of the malfunctioning cells to persist for longer periods of time. [11]
Morphogenesis is the coordination of cell adhesion, migration, and signaling to create structure and form in an organism.

A cell becomes cancerous when its mechanisms for controlling
Cancer thus only occurs when both the mechanisms regulating cell growth and the mechanisms for destroying cancerous cells do not function properly.
this can cause harm by sequestering nutrients, rerouting bloods flow, applying pressure Cancer drugs commonly work by selectively harming cells that undergo rapid growth
