سيرة الحياة

ولد روبرت بول لانزا في بوسطن ، ماساتشوستس، ونشأ في الجنوب من هناك، في ستوكتون، ماساشوستس. لانزا "أنجز تغيير جينات الدجاج في قبو منزله"، وجاء اهتمام الباحثون إليه في مدرسة هارفارد الطبية عندما ظهر في الجامعة مع نتائجه. جوناس سالك ، B. F. سكنر و كريستيان بارنارد لانزا قام بإرشادهم على مدى السنوات العشر التى تلت.[2] حضر لانزا في جامعة بنسلفانيا ، وتلقي البكالوريوس ودرجة دكتوراه في الطب. هناك، كان بنيامين فرانكلين الباحث والباحث العلمي جامعة. كان لانزا يستفيد من منحة فولبرايت. وهو يقيم حاليا في كلينتون، ماساتشوستس.


المجهود العلمى

أبحاث الخلايا الجزعية

Lanza being interviewed by Barbara Walters.

Lanza was part of the team that cloned the world's first early stage human embryos for the purpose of generating embryonic stem cells.[3][4] Lanza demonstrated that techniques used in preimplantation genetic diagnosis could be used to generate embryonic stem cells without embryonic destruction.[5]

In 2001, he was also the first to clone an endangered species (a Gaur),[6] and in 2003, he cloned an endangered wild ox (a Banteng)[7] from the frozen skin cells of an animal that had died at the San Diego Zoo nearly a quarter-of-a-century earlier.

Lanza and his colleagues were the first to demonstrate that nuclear transplantation could be used to reverse the aging process[8] and to generate immune-compatible tissues, including the first organ grown in the laboratory from cloned cells.[9]

Lanza showed that it is feasible to generate functional oxygen-carrying red blood cells from human embryonic stem cells under conditions suitable for clinical scale-up. The blood cells could potentially serve as a source of “universal” blood.[10][11]

His team discovered how to generate functional hemangioblasts (a population of "ambulance" cells[12]) from human embryonic stem cells. In animals, these cells quickly repaired vascular damage, cutting the death rate after a heart attack in half and restoring the blood flow to ischemic limbs that might otherwise have required amputation.[13]

Recently, Lanza and a team led by Kwang-Soo Kim at Harvard University reported a safe method for generating induced pluripotent stem (iPS) cells.[14] Human iPS cells were created from skin cells by direct delivery of proteins, thus eliminating the harmful risks associated with genetic and chemical manipulation. This new method provides a potentially safe source of patient-specific stem cells for translation into the clinic. [15] Lanza and Advanced Cell Technology expect to start the process for regulatory approval of what experts said would be the first human trial involving induced plutipotent (iPS) stem cells created by reprogramming adult cells back to an embryonic-like state. They want to test blood-clotting particles, called platelets, made from such reprogrammed cells. Platelets don't carry the risk of genetic defects because they don't have DNA.[16]

Clinical trials for blindness

Lanza’s team at Advanced Cell Technology has succeeded in getting stem cells to grow into retinal cells.[17] With this technology, some forms of blindness may be curable,[18] including macular degeneration and Stargardt disease, currently untreatable eye diseases that cause blindness in teenagers, young adults, and the elderly.

Advanced Cell Technology has received approval from the Food and Drug Administration for human trials using human embryonic stem cells to treat degenerative eye diseases.[19][20] This treatment for eye disease uses stem cells to re-create a type of cell in the retina that supports the photoreceptor cells needed for vision. These cells, called retinal pigment epithelium (RPE), are often the first to die off in age-related macular degeneration and other eye diseases, which in turn leads to loss of vision. Several years ago, Lanza’s team found that human embryonic stem cells could be a source of RPE cells, and subsequent studies found that these cells could restore vision in animal models of macular degeneration.[21]

In recent studies, the same team of researchers showed that their stem-cell therapy provides a long-term benefit in animal models of vision loss.[22] The retinal cells achieved near normal function in animals that otherwise would have gone blind.

In September 2011, Lanza’s company received approval from the UK's Medicines and Healthcare products Regulatory Agency to begin the first human embryonic stem cell trial in Europe.[23][24] Surgeons at Moorfields Eye Hospital in London will inject healthy retinal cells into the eyes of patients with Stargardt's macular dystrophy, hoping to slow, halt or even reverse the effects of the disease. The first person received the embryonic stem cell treatment earlier this year (2012). The patient reports improved vision in the eye treated with the cells, which The Guardian said “represents a huge scientific achievement.”[25]

First published report of embryonic stem cells in humans

Dr. Lanza and his colleagues at UCLA’s Jules Stein Eye Institute published the first-ever report of the medical use of human embryonic stem cells transplanted into human patients.[26] The researchers initiated two prospective clinical studies to establish the safety and tolerability of subretinal transplantation of hESC-derived retinal pigment epithelium (RPE) in patients with Stargardt’s macular dystrophy and dry age-related macular degeneration.

After surgery, evidence confirmed cells had attached and continued to persist during the study. The researchers did not identify any signs of hyperproliferation, tumorigenicity, or ectopic tissue formation in either patient.

The patients who received the human embryonic stem cell transplants say their lives have been transformed by the experimental procedure.[27] During the 4-month observation period neither patient lost vision. Best corrected visual acuity improved from hand motions to 20/800 (and improved from 0 to 5 letters on the Early Treatment Diabetic Retinopathy Study [ETDRS] visual acuity chart) in the study eye of the patient with Stargardt’s macular dystrophy, and vision also seemed to improve in the patient with dry age-related macular degeneration.[26] One of the patients no longer needs a large magnifying glass to read and can reportedly thread a needle, and the other has begun to go shopping on her own.[28] The future therapeutic goal of these studies will be to treat patients earlier in the disease processes, potentially increasing the likelihood of visual rescue.[26]

Biocentrism

المقالة الرئيسية: Biocentric universe

In 2007, Lanza's article titled "A New Theory of the Universe" appeared in The American Scholar.[29] The essay addressed Lanza's idea of biocentric universe, which places biology above the other sciences.[30][31][32] Lanza's book "How Life and Consciousness are the Keys to Understanding the Universe" followed in 2009.[33] Reception to Lanza's theory has been mixed.[34]

Awards and public commentary

Lanza has received numerous awards, including the 2013 “Il Leone di San Marco Award in Medicine” (Italian Heritage and Culture Committee, along with Regis Philbin, who received the award in Entertainment),[35] a 2010 National Institutes of Health (NIH) Director’s Award for “Translating Basic Science Discoveries into New and Better Treatments”;[36] a 2010 “Movers and Shakers” Who Will Shape Biotech Over the Next 20 Years (BioWorld, along with Craig Venter and President Barack Obama);[37] a 2005 Wired magazine "Rave Award" for medicine “For eye-opening work on embryonic stem cells”,[38] and a 2006 Mass High Tech journal “All Star” award for biotechnology for “pushing stem cells’ future”.[39][40]

Publications

Lanza has authored and co-edited books on topics involving tissue engineering, cloning, stem cells, and world health.
