    Transgenic markers for mammalian chimeras (1988)
    Springer
    Development genes and evolution 197 (1988), S. 63-65 
    Details
    ISSN: 1432-041X
    Keywords: Chimeras ; In situ hybridization ; Mice ; Transgenic

    Topics: Biology
    Notes: Summary We describe the construction of aggregation chimeras between normal and transgenic embryos containing multiple copies of mouse β-globin genes. The transgenic component of the chimeras is then detected in tissue sections by a DNA-DNA in situ hybridization technique, using a biotinylated DNA β-globin probe and an avidin-linked alkaline phosphatase detection system. The general advantages of transgenic markers for chimeras are discussed.

    Sperm enzyme activity analysis in individual sperm for detection of heritable mutations in mammals (1988)
    Springer
    Cellular and molecular life sciences 44 (1988), S. 253-254 
    Details
    ISSN: 1420-9071
    Keywords: Mice ; heritable mutations ; sperm enzyme activity

    Topics: Biology , Medicine
    Notes: Summary Male mice were injected i.p. with 2.5 mg/kg mitomycin C, 100 mg/kg ethyl nitrosourea or saline and mated with untreated virgin females five weeks later. Sperm from 64 of the F1 male progeny were analyzed histochemically for acrosin, succinic dehydrogenase and alpha-glycerophosphate dehydrogenase activity. The frequency of F1 males with sub-normal sperm enzyme activity was significantly higher among progeny from treated males than in controls. These results show that analysis of sperm enzyme activity in F1 males is a practical method for detection of transmitted mutations induced in a treated parent.

    Selection for weight gain in mice at two ages and under ad libitum and restricted feeding (1988)
    Springer
    Theoretical and applied genetics 75 (1988), S. 415-423 
    Details
    ISSN: 1432-2242
    Keywords: Mice ; Selection ; Gain ; Feed restriction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Direct and correlated responses in weight gain and body weights were assessed for nine generations of within-family selection. Four selection criteria were used: gain between 28 and 38 or 48 and 58 days of age, and under two feeding regimes, i.e. ad libitum consumption or 80% of the control line. Direct responses to selection and realized heritabilities in the ad libitum lines were greater in the first period. Weight gain under ad libitum feeding at later ages appeared to have a lower genetic variability. In the restricted lines the responses and realized heritabilities were higher in the second period. Selection under restricted feeding in both periods led to animals that had lower weight gains than the control line when compared under ad libitum feeding.

    Selection for weight gain in mice at two ages and under ad libitum and restricted feeding (1988)

    Details
    ISSN: 1432-2242
    Keywords: Mice ; Selection ; Body composition ; Gain
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Correlated responses in feed efficiency, feed consumption and body composition were investigated after nine generations of selection for weight gain in two age intervals, 28 to 38 or 48 to 58 days old, and under ad libitum feed consumption or intake restricted to 80% of the control lines. Correlated responses in feed efficiency and feed consumption in the ad libitum lines were positive in the early period and negative in the late period. Restricted lines had a positive response in feed efficiency and a negative response in consumption in both periods of selection. Changes in body composition in the early period were the same in all selected lines: a lower crude protein percentage at the start of the period and a lower ash percentage at the end of the period. Body composition at the start of the late period was not altered by selection, while at the end of the period ad libitum lines had higher dry matter percentages and restricted lines had lower fat and higher ash percentages. Body composition at 100 days old was not affected by selection except for dry matter percent, which was lower in the restricted lines.

    Phenotypic and genetic variability of estimated growth curve parameters in mice (1988)
    Springer
    Theoretical and applied genetics 76 (1988), S. 148-156 
    Details
    ISSN: 1432-2242
    Keywords: Growth curve ; Genetic parameters ; Heritability ; Mice
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Data from 1,919 outbred ICR mice were used to examine the potential usefulness of growth curve parameters as selection criteria for altering the relationship between body weight and age. A logistic growth function was used to model growth through 12 weeks of age. Estimates of asymptotic weight (A), maximum growth rate (r) and age at point of inflection (t*) were obtained by nonlinear least-squares. A log transformation was also used to stabilize residual variance. Phenotypic and genetic parameters were estimated for the estimated growth curve parameters and for body weights at 2, 3, 4.5, 6, 8 and 12 weeks of age. Heritabilities of estimated growth curve parameters (obtained with and without a log transformation, respectively) were: A (0.28±0.07, 0.28±0.07), r (0.35±0.07, 0.53±0.09) and t* (0.41±0.08, 0.44±0.08). Estimated genetic correlations suggest that t* may be useful in selecting for rapid early growth without increasing mature weight.

    Divergent selection for in vitro developmental capacity of preimplantation mouse embryos (1988)
    Springer
    Theoretical and applied genetics 76 (1988), S. 467-472 
    Details
    ISSN: 1432-2242
    Keywords: Selection ; Embryo development ; Embryo culture ; Mice
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Replicated divergent selection was conducted for two generations in ICR mice for in vitro developmental capacity (IVDC; percentage of fertilized one-cell zygotes developing to blastocysts in vitro per female donor). Realized heritabilities based on high and low selection were 0.03±0.08 and −0.11±0.09 in replicate 1, and 0.10±0.11 and 0.08±0.10 in replicate 2. No differences were detected between selection lines (P〉0.2) or replicates (P〉0.1). Estimate of heritability in the base population based on 332 daughter-dam pairs was 0.14±0.18. These results indicate that additive genetic variance contributes little to the phenotypic variance in this trait. Considerable phenotypic variation in IVDC was observed (mean=49.3; SD=31.0), with a range of IVDC from 0%–100%. Utilization of donor female as a blocking factor is suggested for designs of experiments with preimplantation embryos to increase precision and power of statistical analyses.

    Peripheral neurosecretory cells on the thoracic median nerves of the locust, Schistocerca gregaria (1988)
    New York, NY : Wiley-Blackwell

    Notes: The distribution of neutral red staining peripheral cell bodies along the nerve trunks of the thoracic median nervous system of the locust, Schistocerca gregaria, is described. Backfilling of the cells with cobalt chloride solution reveals that they are neurones with characteristic axonal processes that terminate in the neurohaemal areas of the median nerve. The neurones react with the dye acridine orange, indicating their neurosecretory nature. This is confirmed by their ultrastructural appearance at the electron microscope level. The distribution and staining properties of the cells are compared with those of peripheral neurones from other insects and the nature of their neurosecretory product is discussed.

    Notes: Numerous functional ergatoid replacement reproductives were found in one colony of Nasutitermes columbicus in Panama. Their morphology was mainly workerlike, although several imaginal characters such as the compound eyes and variable wing buds were more or less developed. The sex organs were fully mature and the fat body of the females, not of the males, was of the “royal” type. The development of the eyes was not accompanied by the differentiation of the optic lobes of the brain, nor was the presence of wing buds correlated with a development of the wing muscles.

    Some aspects of segment formation and post-placental development in Peripatus acacioi marcus and marcus (Onychophora) (1988)
    New York, NY : Wiley-Blackwell

    Notes: The surface morphology of the anterior-to-posterior sequence of segment formation in embryos of a viviparous neotropical onychophoran and aspects of post-placental development seen using scanning electron microscopy are described. When all the segments have formed and the walking legs have completed their elongation, the body surface becomes covered with an embryonic cuticle that does not exhibit the hydrofuge properties seen in the adult cuticle. As soon as the walking legs have reached their full length, barbed projections are formed at their distal extremities. These projections are extensions of single cells and are covered by the embryonic cuticle. Transmission electron microscopy reveals that the cells at the distal ends of the legs and their projections have many pinocytotic vesicles at their surfaces. The cytoplasm of these cells and their projections is rich in mitochondria, rough endoplasmic reticulum, glycogen, and granules of storage material. There are minor differences in the surface morphology of the projections found at the ends of the walking legs in embryos of Peripatus acacioi and those of Peripatus biolleyi. The projections and the embryonic cuticle persist thoughout postplacental development. The role of the projections in the uptake of material by the embryo from the uterus is discussed and the possible phylogenetic significance of these projections is suggested.
