Introduction The constant advances in health and hygiene over time such as the standardization of processes, implementation of laws and improvements in health (along with other factors) have increased the overall average life expectancy to about 70 years. Discoveries such as the microscope and microbial theory made vaccines and antibiotics possible, which allowed us to defend ourselves against diseases, but now, with the technological improvements of this century we can do it from its origin, genes.
The objective of this report is to know about the technological advances in the area of ??health and the ethical problems that these pose to reflect on the future that they promise us through the most outstanding research in their field. First, it begins by describing what HeLa cells are, their discovery and their important role in modern medicine. Then the issue of genetic editing is discussed where its main problem and its delicate but essential role in the future for the treatment of diseases that affect our health are explained and, finally, we talk about how the use of Nanotechnology in the human body could change our lifestyle forever.
The methodology with which we worked was a review of bibliographic sources.
Behind one of the most important discoveries of the last century is the case of Henrietta Lacks, a cervical cancer patient who died in 1951 when this disease ended her. In one of his visits to the doctor, a sample of carcinogenic tissue (which causes cancer or favors its appearance) was extracted for research purposes, this being a common practice at that time. When they took the cells to the laboratory, it was observed that they kept reproducing. Even for a carcinoma where its main characteristic is to refuse to die, having them in a laboratory is another story since they only survive for a few days making any research on them very difficult. HeLa cells (named after the initials of their first and last names) could be grown in a laboratory indefinitely. Even when their original carrier had died, their cells would continue to replicate in a culture medium, and they continue to do so. After the discovery copies were distributed to any scientist who asked for them with the sole intention of benefiting science, thus giving the world the first immortal cell line which has contributed over the decades to countless advances not only medical , also in radiation and toxic substances, tests in space and even in cosmetics. But perhaps the greatest utility about the Hela line is in genetics, since for the first time you can study the effects of human genome editing in the short and long term, thanks to this you can achieve extraordinary progress in the area of ??hereditary diseases such as color blindness, myopia, anemia and Down syndrome among many other pathologies that would otherwise take time to resolve.
The genetic edition is one of the greatest promises of the 21st century as it poses solving virtually any problem of our health in a laboratory with the famous CRISPR technique.
