핵심 특성
주요 업적
1952년 세인트루이스의 빅토어 함부르거 연구실에서 레비몬탈치니는 생쥐 종양을 닭 배아에 이식하면 종양과 직접 닿지 않아도 감각신경과 교감신경이 자란다는 것을 보였고, 종양이 주변으로 퍼져 나가는 신경 성장 촉진 인자를 내놓는다고 결론지었다. 그녀는 이 인자를 측정하는 배양 검정법을 개발했으며, 1953년 연구진에 합류해 이를 정제한 생화학자 스탠리 코언과 함께 신경 성장 인자(NGF)를 발견했다. 노벨 총회는 NGF를 이후 잇따라 발견된 성장 조절 신호 물질들 가운데 맨 처음 발견되어 규명된 것의 하나로 설명한다.
이 성장 인자 발견의 공로로 레비몬탈치니와 코언은 1986년 노벨 생리의학상을 공동으로 받았고, 같은 해 앨버트 래스커 기초의학연구상도 함께 받았다. 노벨 총회는 이 발견이 기초과학에 새로운 분야를 열었으며, 이후 새로운 성장 인자를 찾아낸 모든 연구 집단이 두 사람이 낸 길을 따라간 것이라고 밝혔다.
그녀의 발생학 연구는 발달 중인 신경세포가 표적 조직에 의존한다는 점을 시사했다. 1940년대 초 토리노에서 사지를 제거하면 신경세포가 생겼다가 죽는다는 것을 알아냈고, 1949년 함부르거와 함께 이를 넓혔으며, 1960년에는 바버라 부커와 함께 NGF 항혈청이 신생 생쥐의 교감신경계 대부분을 파괴한다는 것을 보였다. 노벨 총회는 발달 과정에서 신경세포가 넘치게 만들어지고 NGF를 내는 표적에 닿은 것만 살아남는다고 설명하는데, 이 생각은 신경영양 가설로 알려져 있다.
삶의 장면들
1940년대 초 토리노에서 레비몬탈치니는 침실에 차린 작은 실험실에서, 임시로 만든 부란기와 바느질 바늘로 만든 수술 도구, 농장에서 사 온 수정란으로 빅토어 함부르거가 했던 닭 배아의 사지 싹 제거 실험을 되풀이했다. 그녀는 여러 시점에 걸쳐 배아를 살펴 신경세포가 처음에는 늘어나다가 나중에 죽는다는 것을 확인했고, 사라진 사지가 신경세포가 형성되도록 하는 인자가 아니라 이미 생긴 세포를 유지하는 데 필요한 인자를 내놓지 못한 것이라고 결론지었는데, 이는 함부르거와 다른 해석이었다.
발표된 결론을 더 촘촘한 자료로 다시 시험하고, 자료를 따라 다른 설명에 이르는 방식과 일치한다. 분석적 엄밀성
1952년 종양 추출물을 닭 배아에 주사하는 방법으로는 이식한 생쥐 종양이 일으키던 신경 성장을 재현하지 못하자, 레비몬탈치니는 종양이 생긴 생쥐 두 마리를 핸드백에 넣고 리우데자네이루로 날아가 헤르타 마이어의 조직 배양 실험실에서 연구했다. 자신의 연구 시설에는 그럴 만한 설비가 없었기 때문이다. 여러 차례 부정적인 결과가 나온 뒤, 종양 조각에 닿지 않게 곁에 둔 닭 배아 신경 조직에서 약 10시간 만에 신경 섬유가 빽빽한 후광 모양으로 뻗어 나왔다.
자신의 연구실에 없는 수단을 다른 곳에서 찾아내 실험을 해내는 모습과 일치한다. 자원 활용 성향
전환점
1946년 빅토어 함부르거는 전쟁 중에 발표된 레비몬탈치니의 닭 배아 사지 제거 연구 논문을 읽고, 서로 다르게 나온 결과를 함께 따져 보자며 그녀를 세인트루이스의 워싱턴 대학교로 한 학기 동안 초청했다. 그녀는 1947년에 도착했고, 한 학기는 약 30년으로 이어졌으며, 함부르거와 함께 낸 1949년 논문과 이후의 신경 성장 인자 연구가 이곳에서 나왔다.
같은 자료를 두고 해석이 갈릴 때, 다른 해석을 가진 연구자와 함께 실험하며 결론을 가리려는 모습과 일치한다. 협업 성향

Orientation only; not used as support for any row.
- The Nobel Assembly at the Karolinska Institute, press release for the 1986 Nobel Prize in Physiology or Medicine (awarded jointly to Stanley Cohen and Rita Levi-Montalcini 'for their discoveries of growth factors') -- CANONICAL SIGNIFICANCE SOURCE: the Assembly's account that nerve growth factor (NGF) and epidermal growth factor were the first of many growth-regulating signal substances to be discovered and characterized; that Levi-Montalcini, then in Viktor Hamburger's laboratory in St. Louis, showed in 1952 that mouse tumours transplanted to chick embryos induced growth of sensory and sympathetic nerves without direct contact and concluded that the tumour released a nerve growth-promoting factor; that she developed the culture bioassay for NGF (the ganglion 'halo'); that the biochemist Stanley Cohen joined the group in 1953, purified the active extract, found the unexpected snake-venom activity and the mouse salivary-gland source (1958) and made antibodies; that excess nerve cells are produced in development and only those reaching a target that makes NGF survive; and that all groups that later found new growth factors followed in the tracks of Levi-Montalcini and Cohen.

- Nobel Foundation, 'Rita Levi-Montalcini - Biographical' (the autobiographical essay she wrote at the time of the 1986 award, published in Les Prix Nobel 1986) -- SELF EVIDENCE: her own chronology (medicine at Turin, the home research unit in her bedroom from 1940 inspired by a 1934 paper by Hamburger, the move of the laboratory to a country cottage, Hamburger's invitation to St. Louis, professorships there to 1977, a research unit in Rome from 1962 and the directorship of the CNR Institute of Cell Biology 1969-1978). Used only for orientation and chronology and to check dates against other sources; never as sole support for any row or card. Its family, wartime and refugee-camp passages were not used, and its date for the racial manifesto (1936) conflicts with other sources (1938). Read in full.
- Lasker Foundation, 'Growth factors - NGF and EGF' (1986 Albert Lasker Basic Medical Research Award to Rita Levi-Montalcini and Stanley Cohen: citation and narrative) -- award-body account that her initial observation of nerve fibres growing into tumour tissue led to studies concluding that a soluble substance released by the tumour caused the effect, that tumour tissue implanted in the egg membrane without contact still drove nerves into inappropriate organs, that she devised a simple in vitro assay still in use, that she pursued increasingly refined NGF studies in collaboration with Cohen and others, and that her work was done without techniques later investigators took for granted. Its wording credits her with finding the same substance in snake venom and mouse salivary glands, which the Nobel press release, Cohen and the PNAS profile attribute to Cohen. Honouring in tone (promotional adjectives not used). Read in full.
- Diana Lutz, 'Obituary: Nobel Laureate Rita Levi-Montalcini', The Record, Washington University in St. Louis, 8 January 2013 -- university obituary: her 1947-1977 research at Washington University; the repeat of Hamburger's limb-bud experiments in her makeshift bedroom laboratory, where studying the nerve cells at more frequent intervals led her to a different conclusion (cells proliferate and then die for lack of a maintenance factor); the fertilised eggs bought from neighbouring farms; an early curriculum vitae in the university archives listing 1940-1945 as a private laboratory; Hamburger's invitation in 1946; the tumour-bearing mice flown to Rio de Janeiro; Cohen's snake-venom surprise and the 1959 antiserum; the little recognition the work received at first; colleagues' recollections (Dehner, Allen, Woolsey); and the controversy over the Nobel committee's exclusion of Hamburger. Institutional obituary with named colleagues, admiring in tone; its note that she became director of the Institute of Cell Biology in 1962 conflicts with her own date of 1969. Read in full.
- Washington University in St. Louis, 'Remembering Rita Levi-Montalcini', The Source, 10 October 2013 -- announcement of a memorial gathering with colleagues' and a former student's recollections: that Hamburger invited her in 1946 so that they could reconcile their disparate findings, that she became a full professor in 1958 and then established a research centre in Rome, and a student's account of her as a demanding but fair teacher.
