These mass repositories of DNA profiles enable the police to identify DNA stains which are found at crime scenes and are invaluable in criminal investigation. Governments have always brushed aside privacy objections by stressing that the stored DNA profiles do not contain sensitive genetic information on the included individuals and that they reside under the statutory privacy protection regulations. However, it has been generally overlooked that the police also store the DNA samples from which the DNA profiles are derived. Although these DNA samples are actually a potential source of genetic information, they have so far scarcely been the subject of discussion. In this article we will show that both European and national regulations offer inadequate protection to completely prevent function creep, that is, the use of these forensic DNA samples for purposes beyond those envisaged at the time of collection.

We evaluate the various values donors may attach to cells and that may influence their decision to donate. Awareness of the various meanings of the value of the cells is therefore essential for all involved in cell transfer. We discuss four types of value: biological, relational, material and informational value and discuss their relevance for collection, for the relationships that are established between donor and cell collector and for informed consent procedures. The actual setting of cell donation and the contents of informed consent can either maintain or disrupt these relationships. While one can exclude donors from any further say in the destination of their cells and from any financial return, one cannot exclude them from a persistent interest in the genetic information of the cells.

One of them is the ability to adhere and invade pocket epithelium. The aim of this study was to follow, over time, the association of P. gingivalis and consequent morphological changes of the pocket epithelium cells. The association capacity of four P. gingivalis serotypes [K1, K2, K4, K- (nonencapsulated)] with in vitro cultured mono-layers from periodontal pocket epithelial cells of patients with periodontitis, was followed by fluorescence microscopy and bacterial culture. The contact time between bacteria and epithelium cells ranged from 45 min to 8 h. The microscopic evaluation allowed differentiation between dead and living cells (bacteria as well as epithelium) and description of the morphological changes after association. A highly significant difference in the number of associating bacteria was found between dead and living epithelium cells, and between non-capsulated and capsulated strains. A significant increase in the proportion of dead pocket epithelium cells was found with prolonged association time. The morphological changes (rounding of the epithelial cell, detachment from the glass cover-slip and loss of intercellular contact) occurred faster for mono-layers inoculated with the non-encapsulated P. gingivalis strain. This study indicates that dead pocket epithelium cells harbor more P. gingivalis cells, and that a positive correlation exists between contact time and cell death. For the P. ginigvalis species, non-encapsulated strains associate in higher number. As a result, the damage they cause to the host cell seems to occur faster than occurs in encapsulated strains. As such, cell death can be seen as the end-result of bacterial association.

The databases Pubmed, Google Scholar, Psychinfo, Biological Abstracts, Francis, Anthropological Index online, Web of Science, and Sociological Abstracts were searched using key words for the period 1990-2004. Studies were included if they were published in a peer reviewed journal in English and described the attitudes of minors, parents or healthcare professionals towards carrier testing in minors in a family context. The results were presented in a summary form. In total 20 relevant studies were retrieved (2 studies reported the attitudes of two stakeholders). Only one study reported the attitudes of adolescents, two studies reported the attitudes of adults who had undergone carrier testing in childhood. In total six studies have been retrieved discussing the parental attitudes towards carrier testing in their children. Over all studies, most parents showed interest in detecting their children's carrier status and responded they wanted their child tested before the age of majority ; some parents even before 12 years. Eights studies were retrieved that reported the attitudes of relatives of affected individuals. Most were in favor of carrier testing before 18 years. The studies retrieved suggest that most parents are interested in the carrier status of their children and want their children to be tested before they reach legal majority (and some even in childhood). This can lead to tensions between parents and healthcare professionals regarding carrier testing in minors. Guidelines of healthcare professionals advise to defer carrier testing on the grounds that children should be able to decide for themselves later in life to request a carrier test or not.

Moreover, the storage of DNA profiles in forensic databases can aid the fast resolution of crimes. Biobanks are repositories of such human tissue and can have a strategic importance for genetic research, clinical care, and future treatments. However, storage and use of biological specimens also raise a number of ethical questions. What are the risks associated with participating in biobank research? How should privacy and confidentiality be protected? As in other medical research, informed consent is an important prerequisite, but what is the scope of this consent? Can such consent be implicit? What if information that may be relevant to the donor of the material is found during research? Should this information be returned to the participant and by whom? Does the concept of human dignity apply to human tissue? Can human tissue truly be owned by researchers or institutions? These ethical questions are complicated if research participants are minors, and different aspects may be important depending on the cultural context.
