The spine is a column of 24 moveable bones called vertebrae that are connected to one another by ligaments. Treatment can include medications, physical therapy, injections, or surgery. Pain results from stressed joints and pinched nerves, not the abnormal curve. Moderate deformity occurs when the facet joints and discs deteriorate over time and are no longer able to support the spine's normal posture. Adult scoliosis and kyphosis can be caused by age-related wear and tear on the back or complications from past surgeries. Spinal deformity is an abnormal alignment or curve of the bony vertebral column. Research suggests that this "blebbing" is caused by an imbalance in the proteins that constitute the nuclear lamina which leads to separation of the lamina fibers.Spinal Deformity: Adult Degenerative Scoliosis Overview Cancer cell nuclei are frequently misshapen and bulges known as “blebs” can often be observed in cells’ nuclear membranes. One of these structural components is the nuclear lamina. Several structural components are involved in the regulation of nuclear morphology. Nucleus: In normal cells, the nucleus has a smooth appearance and maintains a uniform, spheroid shape. Researchers have been investigating the relationship between cancer cell shape and a patients’ outlook, and whether cell shape may also help to distinguish between the different types of cancer. Cancer cells are misshapen, and appear as a chaotic collection of cells, in an array of shapes and sizes. Different types of cells do not look alike, but, if you analyze cells of the same cell type they will look extremely similar, maintaining a uniform shape.įor years researchers have been peering down microscopes, looking for distinct features that can help them determine the difference between a cancer cell and normal cell. Normal cell vs cancer cell – the key differencesĬell shape: Normal human cells come in many shapes and sizes – as they differentiate and adopt specialized functions their shape changes accordingly – for instance, a red blood cell looks very different to a nerve cell.

"Hallmarks of Cancer" is a term used to describe the specific characteristics that distinguish cancer cells from normal cells.įigure 1: The 10 hallmarks of cancer, as defined by Douglas Hanahan and Robert A. The genetic changes that contribute to cancer usually affect three specific types of gene proto-oncogenes, tumor suppressor genes and DNA repair genes. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it. In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. These changes disrupt normal cell function – specifically affecting how a cell grows and divides.

The body is made up of approximately 37.2 trillion human cells – so you can truly appreciate how many that is, here is the number written out in full, 37,200,000,000,000 – that’s a lot of cells.
