This edition of the BMBL remains an advisory document recommending best practices for the safe conduct of work in biomedical and clinical laboratories from a biosafety perspective, and is not intended as a regulatory document although it is used that way by some.

Not illustrated. 1921 Excerpt: ...made from two agar slants," or "1 e. c. of a beef broth culture." Unfortunately such statements are still appearing in bacteriological literature, but they are fast becoming meaningless. Bacterial cultures are not comparable unless grown under identically the same conditions for the same length of time, and inoculated from the same kind of parent culture. In the results presented in this paper effort has been made to lay special emphasis upon these points. Early in our experience with the mouse protection test for determining the potency of antipneumococcic serum we realized the inadequacy of the test in so far as the so-called "border-line" serums were concerned. Not so plainly evident are the weak points of such a test applied to a very good serum or to a very poor one--that is, in either case fairly constant results may be obtained. THE PROTECTION TEST. The complete details of the potency test for antipneumococcic serum as conducted at the Hygienic Laboratory are given in the Public Health Reports for November 21, 1919, page 2663. In brief the method is as follows: White mice are selected weighing from 15 to 20 grams. They are injected intraperitoneally, the serum first and the culture immediately afterwards. The serum is diluted with saline solution (0.85 per cent) so that 0.2 c. c. is contained in 0.5 c. c. of the dilution. The culture is diluted with broth (plain or glucose) so that 0.1 c. c. is contained in 0.5 c. c. of dilution. At the same time 8 mice are inoculated with the culture alone highly diluted. These culture control mice receive 0.00,000,1 c. c., 0.00,000,01 c. c., 0.00,000,001 c. c., and 0.00,000,000,1 c. c. of the culture used for the teat, 2 mice to each dose. To maintain the organisms in an actively virulent c...

The makings of future news headlines about tomorrow's life saving therapies starts in the biomedical research laboratory. Ideas abound; early successes and later failures and knowledge gained from both; the rare lightning bolt of an unexpected breakthrough discovery --- this is a glimpse of the behind the scenes action of some of the world's most acclaimed stem cell scientists' quest to solve some of the human body's most challenging mysteries. Stem cells --- what lies ahead? The following chapters explore some of the cutting edge research featuring stem cells. Disease and disorders with no therapies or at best, partially effective ones, are the lure of the pursuit of stem cell research. Described here are examples of significant progress that is a prologue to an era of medical discovery of cell-based therapies that will one day restore function to those whose lives are now challenged every day --- but perhaps in the future, no longer.

Stem Cells: Scientific Progress and Future Research Directions

The major purpose of this conference was to bring together a number of people from various scientific fields to consider a topic so broad that a cross-disciplinary approach to it could be effective. To this end, the planning group invited molecular biologists, embryologists, biologists, psychologists, sociologists, anthropologists, and clinicians to examine within a short period the topic of sexual differentiation, which involves the consideration of molecules, man, and society, with overtones of mysticism, religion, and social organization. The topic represents an area in which there is evidence of environmental influences on genetic expression and one in which an interaction of behavioral and biological disciplines can be readily demonstrated. The ability to pass from concern with molecules, cells, and anatomical configurations to the holistic concept of the organism is indeed difficult. Molecular biology and other biological disciplines have approached their particular problems with a view to decreasing the variables and arriving at some concept of universal biological law. In contrast, the social science disciplines, instead of reducing variables, examine the many variables that emerge where the organism deals with his brothers and his entire environment. Both systems of thought have utilized the scientific method, but each has approached an examination of developmental phenomena in a different way, accumulating different kinds of data. There was no question in the minds of the conference planners that an examination of such an important topic as sexual differentiation would have to include both these approaches, for it is from both of them that new concepts in this complex area will come. We brought both together in the belief that the message of a concern with the organism must include both.

A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. Gene mutations can be classified in two major ways: • Hereditary mutations are inherited from a parent and are present throughout a person’s life in virtually every cell in the body. These mutations are also called germline mutations because they are present in the parent’s egg or sperm cells, which are also called germ cells. When an egg and a sperm cell unite, the resulting fertilized egg cell receives DNA from both parents. If this DNA has a mutation, the child that grows from the fertilized egg will have the mutation in each of his or her cells. • Acquired (or somatic) mutations occur at some time during a person’s life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if a mistake is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed on to the next generation.
